Hidden Veggie Spaghetti Sauce is a delicious, meatless spaghetti sauce with everyday vegetables like mushrooms, carrots, and celery and includes Instant Pot and stove instructions. Sometimes the secret to getting finicky eaters to eat vegetables is all about how you hide the vegetables. This homemade marinara sauce uses a food processor or box grater to mince (not puree) the veggies that are cooked into the sauce. It's full of hearty flavor, plant-based nutrients, and no weird ingredients.

    Man I was skeptical about how the texture would turn out on this one. Then we made it. Delicious! Looking forward lunch leftovers today. The only thing missing was your homemade French bread 😉

    Hi! I was looking for an easy pasta sauce recipes with lots of veggies to make for my family. I’m a vegetarian, but my children and husband are not, so I needed one that would make everyone happy.

    I’ve attempted to make my own pasta sauce before and it was a failure so I’ve been buying the organic veggie chunky kind at the supermarket.

    I tried this recipe today and just had to come here to tell you that you are so correct about everything you claim this sauce to be! It is delicious, it is veggie packed, it is SO EASY!

    I topped the pasta with freshly grated Parmesan. I made a cucumber, tomato, red onion salad to go with it and had a delicious French bread with pats of butter. Along with a glass of red wine.

    Thank you so much for sharing this recipe. It is most definitely a keeper. It was so delicious. X
