I’ve loved walnuts my whole life, but just recently began to experiment with this tasty ingredient in my recipes.

One of my favorite walnut-inspired meals is this comforting and nourishing veggie baked penne with walnut sauce. The flavor here is incredible, and I love that this dish is packed with so many heart-healthy* ingredients!

Veggie Baked Penne with Walnut Sauce Recipe

Did you know that more than 99% of the walnuts in the U.S. are grown in the fertile soils of California’s Central Valley?

I think that’s really quite remarkable, and it gave me a whole new perspective on my favorite nut.

I’ve really been shifting my thinking about walnuts a bit over the past few years. While I used to view walnuts simply as a snack or a way to add some crunch to my salad, I now truly appreciate how versatile and delicious they can be in my everyday cooking.

Plus, California walnuts have SO many health benefits. Namely, walnuts are a healthy source of fat, and they are rich in omega-3 essential fatty acids.

In other words, California walnuts are wonderfully healthy for your whole family—including your kiddos!

I was inspired to create this veggie baked penne with walnut sauce while trying to utilize some of the fall vegetables that I had on hand.

I love creating simple and wholesome meals for my family, and this one has quickly become a favorite, thanks to my easy walnut sauce that really stands out as the star of the dish.

I’ve found that when using walnuts in sauces, my favorite method is to first toast the walnuts for about 8-10 minutes in the oven at 350°. You’ll know they are perfect when they become aromatic and lightly crisp.

I then stir the toasted walnuts and fresh basil into my sauce to finish it. The toasted walnuts add an incredible flavor and texture to the sauce!

My easy walnut sauce would also work well on spaghetti, or any pasta dish.

My scrumptious walnut sauce pairs deliciously with the pasta and roasted vegetables.

We love the combination of butternut squash, zucchini and onion, but you can easily swap these out for any vegetables you have on hand.
