This high-protein pasta sauce is about to become your weeknight go-to. Creamy, dreamy, and loaded with 20 grams of protein per serving! With roasted red peppers and cottage cheese, this no-cook pasta sauce comes together in no time (we’re talking less than 5 minutes, friends). It’s one of our favorite high protein vegetarian dinners!

Some nights, we channel our inner Gordon Ramsey. On other nights, it’s takeout and cooking shortcuts. For those latter times, let me introduce you to this quick blender pasta sauce that skips the stovetop entirely (and saves you from caving to delivery apps!).
Whether you’re looking for a meatless, high-protein pasta or need a tasty meal on the table in record time, this recipe is a game changer. Pro tip: Pair it with chickpea or lentil pasta to double up on protein!
We’ve Got The Secret Sauce
- Versatile: This sauce can be used in any number of recipes! Pair it with pasta, use it as a dip/spread for bread and veggies, or incorporate it into casseroles and soups.
- Hello, Meal Prep: Blend a double or triple batch ahead of time, then keep it in the fridge for no-fuss meals all week.
- Kid-Friendly And Sneaky Healthy: Trust me, this creamy cottage cheese pasta sauce will win over even the pickiest eaters (and they’ll never guess it’s loaded with good-for-you ingredients!).

Grab These Ingredients
In true LEL fashion, we’ve kept the ingredient list for this roasted red pepper pasta sauce short and sweet. Jump down to the recipe card for exact measurements.
- Fire Roasted Tomatoes: We’ll use these to add a smoky, rich flavor. If you can’t find fire roasted tomatoes, sub regular canned diced tomatoes!
- Cottage Cheese: This makes our sauce ultra-creamy and protein-rich.
- Roasted Red Bell Peppers: For some extra smokiness and a hint of sweetness. (If you have the time, you could also roast fresh peppers until the skins are charred, then peel them off.)
- Fresh Basil: Adds a bright, herbal flavor. You could also sub fresh parsley or dried basil (if you use dried basil, reduce the amount by about 2/3).
- To Serve: You can pair this sauce with your favorite pasta variety, but I find short shapes (like fusilli, farfalle, or radiatori) work best. For an indulgent finish, add fresh mozzarella cheese pearls on top!

Make It Vegan
Veganizing this recipe is actually pretty easy (and just as delish!). Simply swap the cottage cheese 1:1 for silken tofu to keep it creamy and protein-packed. For the mozzarella pearls, use your favorite plant-based alternative or sprinkle on some nutritional yeast.
Most pasta is naturally vegan, but double-check the label to make sure it’s egg-free—chickpea or lentil pasta works perfectly here for an extra protein boost!

It’s As Easy As 1, 2, 3
Once you learn just how quick and easy this pasta sauce with cottage cheese is to whip up, you’ll be making it on repeat! This is an overview of the recipe. Jump to the recipe card for the full printable instructions.
- Cook the pasta according to instructions on package.
- Blend the sauce ingredients until smooth and creamy.

Pasta Trick
Reserve about ½ cup of pasta water before draining the pasta. You can add a splash of this starchy water to the sauce when mixing it with the pasta to help it cling to the noodles and create an even creamier consistency!

Please put what actually serving size you are calculating! How can one actual know how many calories they are using
It comes out to about 6 ounces, or 183 grams, per serving of the sauce.
This recipe needs a bit of seasoning. Salt, pepper and some garlic could go a long way.
I love the way the food look,I will definitely try it Blessings
Its good! I accidentally made it with sun ripened tomatoes the first time, and i think it tasted better. But the original is still very good!
Yum! This recipe is almost perfect! It needed a little salt and pepper, and I would add more mozzarella pearls as a personal preference, but it is delicious and so easy!
Hi Sarah, What can I use instead of tomatoes please as I am allergic to them in any form. But I would love to make this if i can.
Thank you for all your recipes in your book, I have made quite a few of them.
All delicious.
Roasted red peppers would work well in their place! 🙂
Thank you for sharing this recipe. Very liquid. Came out a bit bland so I recommend adding salt and pepper. Very filling however. Ended up adding chopped bacon (probably defeats the purpose) which helped.
This is absolutely ridiculous! This sauce has no business tasting as good as it is! I added a little bit of garlic powder, cayenne pepper and Italian seasoning. It took less than a minute to blend. I don’t even want pasta, just a piece of nice crusty bread and a bowl of this amazing concoction. Definitely going into the “making again and often” category. Easy 5 stars and then some.
Thanks so much for the sweet review, you made my day!
So yummy! I loved the addition of the peppers! So easy too- definitely going to be a repeat!
Yay, so glad it was a hit Jan!
What else could I use instead of bell peppers do you think? I hate them!
I would just add more tomatoes!
