This super simple protein pasta sauce with hidden veggies uses just three ingredients and is packed with protein, vitamin A, potassium, and fiber. As a busy mom, it’s one of my favorite ways to balance convenience and nutrition – without making separate meals for everyone. It’s an easy way to upgrade your favorite pasta sauce while adding a boost of nutrients… and it tastes delicious, too!

I decided to experiment with this recipe, not knowing if my two picky toddlers would actually eat it. However, kids love pasta – why not attempt to make it a little more nutritious? I simply added cottage cheese and sweet potatoes to a jarred pasta sauce – and guess what – my kids ate it! I even saved a little sauce and made a pizza with it.
This recipe can be customized to meet you and your family’s preferences. It might just give you inspiration to try this with other recipes as well.

Reasons to Try This Recipe
- It’s super easy – you don’t even have to make pasta sauce from scratch (but you totally could).
- Perfect for a busy weeknight or lazy Sunday. Plus, you could make a huge batch and repurpose it for pizza later in the week.
- This recipe takes a toddler favorite and elevates it – so every bite is a little bit more nutritious. Ideal for kids who don’t eat many vegetables – because they won’t even taste them!
- This is a great meal to get your kids involved with the cooking process, which can help with increased food acceptance. My kids love to add ingredients to a blender and watch it go!

Directions
This recipe uses about a 1/2 jar of pasta sauce and makes about 4-5 servings.
You can put the rest of the pasta sauce in the fridge and use in the next 7 days OR double this recipe and have a lot of leftovers for the week!
Freezing is also an option, but it is not usually recommended as it can change the texture of the cottage cheese. You could freeze the leftover jarred pasta sauce without the cottage cheese, though.

- Bring a large pot of salted water to a boil and cook pasta according to package directions. Reserve about 1 cup of pasta water before draining.
- While the pasta cooks, microwave the frozen sweet potato cubes until soft.
- In a blender, combine the pasta sauce, cottage cheese (or yogurt), sweet potatoes, and ¼ cup of the reserved pasta water. Blend until smooth. Season with salt, pepper, and garlic powder to taste.
- Return the drained pasta to the pot (or a large pan) and pour the sauce over top. Heat on low, stirring to combine.
- Add parmesan cheese and stir until melted. Slowly add more reserved pasta water as needed until the sauce reaches your desired consistency.
- Top with additional parmesan cheese and serve.

The Taste Test
I compared the jarred pasta sauce to the blended protein pasta sauce and I felt like they were very comparable. This is probably why my kids ate this pasta – but I was still SHOCKED. It just goes to show that you could probably customize any pasta sauce to make it healthier!
