How to Store and Freeze Walnut Pesto Pasta
Fridge: Store leftover Walnut Pesto Pasta in an airtight container for up to 3 days. For best flavor retention, avoid mixing in the crunchy garlic breadcrumbs until you're ready to serve.

Reheating: When ready to enjoy, thaw the pasta and pesto overnight in the fridge, then reheat gently in a pan over low heat. Add a splash of reserved pasta water if needed for creaminess.
Serving Tip: For best results, always top with fresh toasted breadcrumbs just before serving to maintain that delightful crunch!
Expert Tips for Walnut Pesto Pasta
-
Watch the Garlic: Sauté garlic until just golden; burnt garlic tastes bitter and can ruin your pesto’s flavor.
-
Taste as You Go: Always adjust seasonings in your pesto. A little extra salt or pepper can make all the difference in your Walnut Pesto Pasta.
-
Pasta Water is Key: Reserve 1/4 cup of pasta water. It helps to achieve that creamy consistency when mixing with pesto, so don't skip this step!
-
Customize Your Nuts: If you're out of walnuts, feel free to use pecans or almonds. This flexibility keeps your Walnut Pesto Pasta fresh and exciting!
-
Don’t Overcook Pasta: Aim for al dente! Overcooked pasta can become mushy and lose texture, especially when tossed with the creamy pesto.

Walnut Pesto Pasta with Crunchy Garlic Breadcrumbs Recipe FAQs
How do I choose ripe ingredients for the walnut pesto?
Absolutely! For the best flavors, select vibrant, fresh basil and parsley, with leaves that are bright green and free from dark spots. Look for firm, unblemished walnuts—ideally, they should have a light color and a fresh, nutty aroma. If using garlic, choose bulbs that are plump and heavy, with no signs of sprouting.
How should I store leftovers of the Walnut Pesto Pasta?
Very important! Store any leftover Walnut Pesto Pasta in an airtight container in the fridge for up to 3 days. To keep the crunchy garlic breadcrumbs fresh and crispy, store them separately in a different container until you're ready to serve the pasta again.
Can I freeze Walnut Pesto Pasta?
Absolutely! For the best results, keep the pesto and pasta separate before freezing. The cooked penne pasta can be stored in the freezer for up to 2 months, while the walnut pesto is good for about 6 months. To freeze, place them in zip-top bags, pressing out as much air as possible. When you're ready to enjoy, simply thaw them in the fridge overnight and reheat gently in a pan.
What should I do if my pesto is too thick?
If your walnut pesto turns out too thick, don't worry! Simply add a little reserved pasta water—1 tablespoon at a time—while mixing. This helps achieve that creamy consistency you’re looking for. If you want a smoother texture, you can also blend in more olive oil until you reach your desired creaminess.
Is this dish suitable for people with allergies?
The Walnut Pesto Pasta is refined sugar-free and can be gluten-free by using appropriate pasta! However, if someone in your household has allergies, be sure to check the ingredient labels carefully, especially for the walnuts and Parmesan. You can easily substitute dairy with nutritional yeast for a dairy-free option.
Can I add vegetables to my Walnut Pesto Pasta?
Very much so! Adding seasonal veggies like sautéed zucchini, bell peppers, or roasted cherry tomatoes can elevate your dish while boosting its nutritional value. Simply cook the vegetables until they’re tender and mix them in with the pesto pasta. The more the merrier!
