Ingredients
Marinara sauce – You can buy your favorite marinara sauce from the store or make your own with chopped tomatoes and herbs/spices.
Mascarpone cheese – Creamy mascarpone cheese adds so much flavor to the dish.
Chicken broth – you can also use vegetable broth, chicken stock, vegetable stock, or even bone broth if you’re looking for ways to add more protein.
Salt – To taste. Adding a bit enhances the other flavors.
How to Make Tomato and Mascarpone Sauce
To make the sauce recipe, just gather up the needed ingredients to get started.
Step One: Combine all the ingredients in a blender or food processor. Blend until smooth.
You’ll have to blend for a short time to get it all smooth.
Some of the sauce might get up onto the sides of the blender, so be sure to power off and use a rubber spatula to scrape it down.
Step Two: Transfer to a saucepan or skillet. Heat until hot, whisking occasionally. Do not let the sauce come to a boil.
Variations
Fresh tomatoes – To make this with a homemade, simple tomato sauce, heat some olive oil in a skillet over medium heat with a chopped garlic clove. Add in a pint of cherry tomatoes. Cook until they burst. Season to taste. Add a tablespoon of tomato paste to thicken. Use in place of the marinara sauce.
Add seasonings – You can easily add garlic, Italian seasoning, black pepper, fresh basil leaves, oregano, chili powder, or any other seasonings that you’d like to the tomato mascarpone sauce.
Add veggies – If you want to make it a thicker sauce or add some more health benefits, you can add chopped spinach, caramelized onions, cooked sliced mushrooms, or even a little bit of kale.
Cheese – You can also add some parmesan cheese to the sauce as well, but just be careful with adding too much as it will make the sauce a lot thicker. In a pinch, swap cream cheese in for the mascarpone.
Spicy – You can make this sauce as spicy as you want. Adding in some red pepper flakes and some chili flakes is a great way to add spice to the dish.
Common Questions
What does this simple sauce pair well with?
While I tend to pair it with low carb options, you can use it on top of any food that you want! This would be delicious on linguine, penne pasta, or any other type of noodles or any other al dente cooked pasta.
I love adding this to chicken cutlets, like this Italian Herb Chicken, and I’ve even drizzled it on top of my cooked veggies as well. It’s delicious with broccoli and zucchini – I promise!
If you’re a fan of cauliflower rice, this is a fun way to add flavor without adding any guilt. I always drizzle a few teaspoons on top of my dishes when I want to change up the flavor a bit. This sauce lets me do that without committing to covering it all.
It is also fun to soak up with some Keto Focaccia or keto garlic bread.
How do I store leftover mascarpone pasta sauce?
Be sure that you let the sauce cool down all the way before storing it in an airtight container. The leftovers do need to be stored in the fridge. I like adding them to a mason jar with a lid.
Can I freeze this homemade sauce?
I don’t recommend freezing this sauce recipe. It’s best served fresh and enjoyed as leftovers over the course of 2-3 days. If you need to make it ahead of time, you can always make it 1-2 days in advance and then have it to reheat and enjoy when you’re ready.
Remember that it can be simple and easy to use the leftover sauce on a variety of dishes, so have fun with the process and enjoy. Since it’s so versatile in the way that it tastes, it doesn’t have to be used for just one meal!

Absolutely love this recipe! I had some frozen lobster ravioli that I needed to cook and needed a sauce for it. I substituted cream cheese for the mascarpone and used some of my homemade marinara sauce I put away every year. Very tasty! A keeper recipe for sure!
This was such a hit! Thank you for loving all the ingredients, can’t wait to try this!
Such a great recipe! Super easy, creamy and tastes amazing – we used it on ravioli, but it would be SO GOOD on so many things. Can’t wait to make it again
