If you’ve made a big batch of walnut pesto and you’re wondering what to do with walnut pesto before it goes bad, you’re in the right place.

The rich, nutty flavor of walnut pesto pairs beautifully with so many dishes that you’ll never get bored of it.
In this post, we’ll explore creative and practical ideas for using walnut pesto so you can enjoy every last spoonful.
Let’s dive in.
Creative Ways to Use Walnut Pesto in Everyday Cooking
Walnut pesto can transform ordinary meals into something special, and here are some of the best ways to put it to work in your kitchen.
1. Swirl It Into Soups and Stews
One of the easiest things to do with walnut pesto is to swirl a spoonful into a warm bowl of soup.
The pesto melts into the broth and adds a deep, savory richness that takes minutes to achieve.
Try it in minestrone, tomato soup, or even a simple vegetable broth.
You can also stir walnut pesto into a hearty beef stew or a creamy potato soup for an instant flavor upgrade.
2. Spread It on Sandwiches and Wraps
Instead of mayo or mustard, spread a layer of walnut pesto on your next sandwich.
It works amazingly well with grilled chicken, turkey, roasted veggies, or even a simple tomato and mozzarella combo.
For wraps, mix walnut pesto with a little Greek yogurt to create a creamy, tangy spread that holds everything together.
This is one of the simplest ways to use walnut pesto if you’re short on time but want big flavor.
3. Toss It With Roasted or Grilled Vegetables
Roasted carrots, Brussels sprouts, cauliflower, and zucchini all love a good toss with walnut pesto.
After roasting your veggies, simply spoon some walnut pesto over them while they’re still hot.
The heat helps the pesto coat everything evenly, and the nutty flavor complements the caramelized edges beautifully.
You can also brush walnut pesto onto grilled corn or portobello mushrooms for a smoky, savory twist.
4. Use It as a Marinade or Glaze for Meat and Fish
Walnut pesto isn’t just for vegetarian dishes.
It makes a fantastic marinade for chicken, pork, or salmon.
Just coat your protein with walnut pesto and let it sit for 30 minutes before cooking.
The oils and herbs in the pesto keep the meat tender while infusing it with incredible flavor.
You can also thin walnut pesto with a little olive oil and lemon juice to create a glaze for grilled shrimp or roasted fish.
Walnut Pesto Beyond the Plate: Dips, Dressings, and More
If you’re still wondering what to do with walnut pesto, think beyond the main course and explore these fun ideas.
1. Turn It Into a Creamy Dip
Blend walnut pesto with Greek yogurt, sour cream, or even mashed avocado to make a creamy dip.
It’s perfect for veggie sticks, pita chips, or crackers.
You can also layer it into a hummus bowl or swirl it into a batch of guacamole for a surprising twist.
This is a great way to use walnut pesto for parties or casual snacking.
2. Whisk It Into Salad Dressings
Walnut pesto makes an instant salad dressing when you whisk it with a little vinegar or lemon juice and olive oil.
Drizzle it over arugula, spinach, or a hearty kale salad.
The pesto clings to the leaves and gives every bite a punch of garlic, basil, and toasted walnut flavor.
You can also toss warm pasta or grains with this dressing for a quick cold salad.
3. Add It to Eggs and Breakfast Dishes
Stir a spoonful of walnut pesto into scrambled eggs or folded omelets.
Spread it on toast or a breakfast sandwich for a savory start to your day.
You can even swirl walnut pesto into a bowl of polenta or grits for a fancy brunch vibe.
Breakfast just got a whole lot more interesting.
4. Mix It Into Grain Bowls and Pasta Salads
Cooked farro, quinoa, or brown rice becomes a meal when you stir in walnut pesto.
Add roasted veggies, chickpeas, and a squeeze of lemon for a complete bowl.
For pasta salad, toss cooked tortellini or penne with walnut pesto, cherry tomatoes, and mozzarella pearls.
This is one of the most satisfying ways to use walnut pesto for meal prep.
How to Store Walnut Pesto So You Can Use It Anytime
Knowing what to do with walnut pesto also means knowing how to store it properly.
1. Refrigerate With a Protective Layer
Store walnut pesto in an airtight jar and press a thin layer of olive oil over the top.
This prevents the pesto from oxidizing and turning brown.
It will keep in the fridge for about a week.
2. Freeze It in Ice Cube Trays
Spoon walnut pesto into ice cube trays and freeze.
Once frozen, pop the cubes into a freezer bag.
Each cube is about two tablespoons, perfect for dropping into soups, sauces, or pasta.
Frozen walnut pesto lasts for up to six months.
3. Vacuum Seal for Long-Term Storage
If you have a vacuum sealer, portion walnut pesto into bags and seal them flat.
This keeps it fresh for months and makes thawing quick.
Just cut off a corner and squeeze out what you need.
So, What to Do With Walnut Pesto?
What to do with walnut pesto comes down to one simple truth: it can go almost anywhere you want a boost of nutty, herby flavor.
You can spread it, swirl it, toss it, or freeze it for later.
Whether you’re dressing up a sandwich or adding depth to a stew, walnut pesto is a kitchen hero.
So don’t let that jar sit in the fridge forgotten.
