You know that feeling? You buy a beautiful bunch of fresh basil or parsley, use about two sprigs for that one recipe, and then stare at the rest wilting sadly in the crisper drawer three days later. It breaks my heart every time, and frankly, it wastes money! I finally stopped the cycle of herb guilt when I started this magic trick. Seriously, learning how to Freeze Fresh Herbs In Olive Oil changed my cooking game completely. It’s so incredibly easy—you just need an ice cube tray and oil—and suddenly those peak summer harvests last all the way through winter. I remember the first time I pulled out a frozen basil cube and dropped it straight into a simmering sauce; it tasted like sunshine. This simple technique is my absolute favorite way to preserve flavor for months!
Why You Should Freeze Fresh Herbs In Olive Oil (The Preservation Advantage)
When it comes to keeping those incredible garden flavors alive, I’ve tried just about everything—drying, vacuum sealing, nothing quite beats this vibrant little method. Why bother with these olive oil cubes instead of just drying your herbs? Trust me, the quality difference is huge, and it really ups your game for general fresh herbs storage.
- The oil acts like a little protective shield for the herbs.
- It’s so much easier than rehydrating dried leaves later on!
- You get perfectly measured flavor bombs ready to go.
Maximize Flavor Retention
The real secret sauce here is the olive oil. Dried herbs are great, but they lose a lot of those bright, volatile oils that make fresh herbs smell so amazing. When you Freeze Fresh Herbs In Olive Oil, the oil locks those aromatic compounds right in! So when you melt that cube later in your pan, you get that intense, close-to-fresh flavor blast, which is exactly what we aim for.
Convenient Portioning for Cooking
I love that this method results in about 12 perfectly portioned little flavor bites. You aren’t dealing with a giant bag of frozen mush that you can’t measure. Whether you need a little seasoning for a quick sauté or a big flavor kick for a simmering sauce, you just pop out one or two cubes. It’s portion control made delicious!
Gathering Ingredients to Freeze Fresh Herbs In Olive Oil
Okay, step two is getting your ingredients together, and I have to tell you, this is the easiest part of the whole process. You really don’t need much fuss, which is why I love it so much! We are focusing on high quality here because whatever you put in the tray is what you’re tasting months from now, right?
Herb Selection and Quantity
You’re going to need about 1 cup of fresh herbs, but don’t pack them down! Think loosely packed—just toss ’em in there. I usually grab whatever is thriving in my garden that week. Basil is my absolute favorite for this, but parsley, oregano, thyme, rosemary, and even sage work miracles when preserved this way. Just stick to herbs you actually like cooking with!
The Right Olive Oil
For the fat component, we need exactly 1/2 cup of olive oil. What kind should you use? Well, if you are freezing basil or parsley, aiming for a good quality extra virgin olive oil is usually my go-to because Mediterranean flavors are my jam. But honestly, if you’re freezing something strong like rosemary that you plan to use for roasting chicken, a more neutral, lighter oil works just as well. Just make sure it’s oil you’d happily eat!
Step-by-Step Guide to Freeze Fresh Herbs In Olive Oil
This is where the magic really happens, and I promise you, it’s not complicated at all! The prep work is maybe ten minutes, and then you just let the freezer do the heavy lifting. You’re looking at about four hours total time, though most of that is just waiting for things to get rock solid. Remember, we want maximum flavor preservation for using these later in things like a quick chimichurri sauce or something savory!
Preparation: Washing and Chopping Herbs
First things first: cleanliness! You absolutely have to wash your herbs really well. Dirt and debris are no good for long-term storage. Once they are washed, this part is non-negotiable: they must be *bone dry*. I mean bone dry. Use paper towels, a salad spinner, whatever you have. If the leaves are wet, they just turn into icy mush instead of blending nicely with the oil. Once they are dry, take your sharpest knife and chop them up nicely—we need them finely chopped so they fit well in the tray compartments.
Filling the Tray and Adding Oil
Grab your standard ice cube tray—no fancy molds needed here! Take your finely chopped herbs and gently distribute them into the compartments. The goal is to only fill each little cube space about two-thirds of the way full with the herbs. Don’t overstuff them! Once the herbs are settled, slowly pour your olive oil right over the top. You want the oil to completely cover every single piece of herb in that little cup. Think of the oil as tucking the flavor in for a long, cold nap.

Freezing and Storing Your Olive Oil Cubes
Now, place that tray carefully into the freezer. Make sure it’s flat so nothing spills, because nobody wants flavor leakage! You have to let them freeze completely solid, and this usually takes about three to four hours, depending on how cold your freezer runs. Once they are hard as little rocks, it’s time to store them properly. Gently pop the frozen cubes out of the tray—a little twist usually does the trick—and immediately transfer them into a heavy-duty, freezer-safe zip-top bag. Make sure you squeeze out as much air as possible before sealing it up tightly. This airtight seal is the best defense against freezer burn!
Expert Tips for Perfect Herb and Oil Cubes
Now that you know the basic steps to Freeze Fresh Herbs In Olive Oil, let’s talk about refining the technique a little bit. Even though this method is super forgiving, a few insider secrets can take your flavor bombs from good to absolutely incredible. Storing these herbs means we want them perfect for whenever you decide to start cooking with frozen herbs months down the line!
Handling Stronger Herbs
Not all herbs behave the same way, you know? If you’re working with heartier guys like rosemary or sage, they have those woody stems that are tougher to chew, even after freezing. For those, I always give them an extra fine chop—almost to a paste consistency—so they distribute better in the oil. Also, since these big flavors can sometimes overpower a cube, I’ll reduce the amount of herb slightly, maybe only filling the tray two-thirds with the herb and giving it a tiny bit more oil buffer. They hold up so well this way!
Using Frozen Cubes in Cooking
The best part is how you use them later. Seriously, forget defrosting! If I’m starting a pan of sautéed mushrooms or kicking off a quick sauce—maybe something fantastic like the flavor base for garlic herb grilled shrimp—I just toss a frozen cube right into the hot pan. The oil melts instantly, and the herbs bloom right there. The only time I soften one up is if a recipe calls for a specific amount of oil *beyond* what the cube provides. If you need exactly two tablespoons of oil, let the cube sit on the counter for five minutes, measure the oil, and then toss the rest of the herb bits in!
Variations: How to Customize Your Freeze Fresh Herbs In Olive Oil
Okay, this method of preserving flavor is fantastic for versatility. Once you master the basic technique to Freeze Fresh Herbs In Olive Oil, you can start getting really creative! Why just stick to pure herbs when you can layer in other flavors that make your cooking even faster later on? This is how you move from just storing food to actually creating convenient, pre-flavored building blocks for amazing meals!
Adding Aromatics to the Oil
This is easily one of my favorite tricks for kicking up the flavor factor before the cubes even hit the freezer. Instead of just plain olive oil, why not infuse it a little bit? Before you pour the oil over the chopped herbs, stir in a few other things to the oil itself. I often add a single clove of garlic that I’ve minced super fine, or sometimes just a nice pinch of red pepper flakes if I know I want a little warmth in the dish I’m making later. Imagine opening your freezer and finding a cube that is essentially basil, garlic, and olive oil all wrapped up perfectly—it’s a dream when you are rushing to make something like garlic butter lobster bites!
Herb Combinations
You don’t have to stick to just one type of herb per cube, either! This is where you can really pre-plan your flavor profiles for the upcoming week or month. If I know I’m going to be making a big batch of pasta sauce or pizza later, I mix Basil and Oregano together—a classic Italian base right there. Or, if I know I’m roasting a chicken or some root vegetables, I combine Thyme and Rosemary. Having these pre-mixed herb bombs means you’re not scrambling for dried jars; you just drop the appropriate aromatic cube right into the pan as your cooking fat.

Storage and Shelf Life for Olive Oil Herb Cubes
Now that you’ve gone through the trouble of perfectly preserving those gorgeous green leaves, we definitely want them to last! Storing anything in the freezer requires a little care, especially when we are dealing with oil, since oil can sometimes start to taste ‘off’ if exposed to too much air over time. My main goal here is to keep the fresh flavor locked in and fight off that terrible freezer burn!
Optimal Freezer Conditions
If you followed my advice earlier and transferred those little flavor bombs into a heavy-duty, zip-top freezer bag, you’re already way ahead! That airtight seal is your absolute best friend against freezer burn and absorbing weird smells from other things lurking in your freezer. If sealed up really tight, these frozen herb cubes are fantastic and maintain their intense quality for a great amount of time—I’d say you can count on them lasting easily six months, and often up to a full year! Seriously, if you see yourself using them within six months, that’s your sweet spot for the freshest taste, but honestly, they hold up much longer than dried herbs ever would.
Serving Suggestions: What to Cook After You Freeze Fresh Herbs In Olive Oil
The preservation part is done, which is awesome, but now we get to the fun part: actually using these little flavor packets! Having these pre-mixed cubes ready to go means throwing dinner together after a long day is a breeze. Since you’ve already locked in that wonderful flavor profile when you chose to Freeze Fresh Herbs In Olive Oil, you just toss the cube in the pan and let it work its magic instantly.
Stirring into Sauces and Soups
This is where herb cubes truly shine because they replace both your cooking fat *and* your seasoning all at once. If you are heating up a jar of marinara, or whipping up a batch of cream of tomato soup, don’t bother melting plain butter or heating up neutral oil first. Just drop one of your herb cubes—say, the basil/oregano mix—right into the saucepan over medium heat. Watch it sizzle and melt, instantly releasing the herb fragrance into the oil. It gives the base of your spaghetti bolognese a head start, making it taste like you simmered it for hours.
Flavoring Sautéed Vegetables
If I’m just quickly sautéing some carrots and onions for a side dish—or even if I’m pan-searing chicken breasts—I always reach for an herb cube. If you’re using rosemary and thyme, drop that cube in immediately. That fragrant oil coats the vegetables perfectly as they heat up, and you don’t have to worry about measuring out three different seasonings. It adds such a lovely depth to something totally simple, like steamed green beans or roasted potatoes you decide to crisp up quick on the stovetop!

Frequently Asked Questions About Freezing Herbs in Oil
I always get so many questions when people see my trays full of frozen flavor bombs! It makes perfect sense; you want to make sure you’re doing this right, especially when you’re spending time getting those herbs ready to freeze fresh herbs in olive oil. Here are the top three things I usually hear readers asking me about when they are first trying this method!
Can I use water instead of olive oil to freeze fresh herbs?
Oh, please don’t! This is a crucial difference we need to talk about. If you use water, you are essentially making ice cubes flavored with herbs. When you freeze herbs in water, they get freezer burn super fast because the water crystalizes and leaches the flavor out. Oil, on the other hand, completely coats the herb particles, protecting them from the harsh freezer air. Plus, the oil is what you’re going to use to cook with later! Water just doesn’t provide that necessary flavor transfer or protection—stick to the oil for best results, even if you’re just looking for simple fresh herbs storage.
How do I know if my frozen herb cubes have gone bad?
Since these are mostly oil and herbs, they last a long time, but they aren’t immortal! You should be looking for three main signs. First, always smell them before you use them; if the oil smells rancid, sharp, or just plain ‘off,’ toss the whole batch. That means the fat has oxidized a bit. Second, check for mold, which shouldn’t happen if they’ve been sealed well, but it’s always worth a peek. Finally, bad cubes usually look really dark or discolored compared to the vibrant green you started with. If they still look bright green and smell earthy, you are good to go! These are great for adding to quick bread batter too, check out these quick bread recipes for inspiration!
What is the best herb to freeze using this olive oil method?
Honestly, the best herb is the one you use the most! That said, tender, soft herbs like basil, parsley, cilantro, and chives absolutely shine in this preparation because their delicate flavors are totally preserved by the oil bath. They stay bright green and potent! However, don’t discount the heartier herbs like rosemary, sage, or thyme. They come out wonderfully too, though you might want to mince them a little finer than the soft ones. A rosemary-thyme cube is just perfect for dropping into the pan next time you roast any kind of meat!
