We love tomato sauce of any kind…but this Rosemary Chicken Sauce is a staple in our house. It’s incredibly light on the stomach, will still fill you up, and tastes amazing!
Chicken breasts or thighs get pan seared and simmer until they’re golden brown. Then they cook until they are fall apart tender in tomato sauce. We serve it over both pasta and zoodles – but it’s delicious no matter how you serve it.

While we love traditional meatballs and sauce, this chicken sauce is a nice change.
The sauce is paleo, Whole30 friendly, gluten free and dairy free – however – you can totally doctor it up if you don’t follow any of those diets. I love it with parmesan cheese on top – and have included some other substitutions for you below!
What makes this chicken sauce healthy?
- Low in fat – Healthy fats are good for us, but typically sauce and meatballs can be high in fat from the meat used, making it somewhat greasy. This sauce is made with chicken breasts, which keep it low in fat and high in protein.
- SO easy– This sauce is so simple to make. I prefer to make it in the crockpot but you can also make it on the stove top in under two hours.
- High Protein – Most pasta sauces/dishes are just carbs on carbs. This sauce is loaded with over 30+ grams of protein per serving.
Let’s make it!
Ingredients for Rosemary Chicken Sauce:
To make this Rosemary Chicken Sauce you’ll need:

- red pepper flakes
- red wine
- canned crushed tomatoes

You can find substitutions for all of these ingredients below in the green shaded box.
How to make Rosemary Chicken Sauce
Making this sauce has a few steps, but I promise it is worth it. Here’s how we make it.
- Heat olive oil in a pan and season chicken with salt and pepper on both sides.
- Sear the chicken 5-6 minutes on each side, over medium high heat until the outside is browned. You’ll have to cook the chicken in 2 separate batches depending on the size of your pan.
- Saute garlic, onion, red pepper flakes, and rosemary for 5 minutes, uncovered over medium heat, until translucent.
- Once translucent, add red wine and cook for another 5 minutes, uncovered.
- Add crushed tomatoes and chicken back to the pot. Bring to simmer. Cover and cook for 1-2 hours on low, stirring every 30 minutes. The chicken will begin to fall apart.
- When ready to eat, gently break apart the chicken. Serve over zucchini noodles or pasta.
The chicken will be so tender it just falls right apart!





Substitutions for Rosemary Chicken:
Chicken: You can make this with boneless chicken thighs or chicken tenders. Either one will work!
Wine: Skip the red wine if you are paleo/Whole30. It’s not necessary but it does add flavor.
Veggies: I have also made this with 1/2 cup each of chopped carrots, celery and mushrooms added and it was delicious. If you don’t have a certain amount of veggies, you can mix and match them with others. A little less carrots or celery, etc – will not drastically affect the taste.
Fresh herbs: I prefer to use fresh rosemary in this recipe. Depending on what you use, I do a 3 to 1 ratio of fresh to dried spices. For example, you can use 3 tablespoons of fresh chopped herbs or 1 tablespoon of dried herbs.
Add Ins: Kalamata olives, fresh herbs or even corn make delicious add ins to this recipe. You could also try this Puttanesca Sauce!

How to serve Chicken with Tomato Sauce
You can serve this Rosemary Chicken Sauce a number of ways. Here are some ideas:
Over pasta or zucchini noodles – This goes great over any pasta or zoodles. I have tips for using zoodles below.
Wonder Noodles – We don’t love wonder noodles as a pasta substitute, we prefer zoodles – but they will work for serving.
Rice or cauliflower rice – This sauce goes great over rice or cauliflower rice.

How to prevent soggy zucchini noodles
I commonly get asked how to avoid watery zucchini noodles. I have two tips for you for how to avoid soggy zucchini noodles.
REALLY squeeze the water out of them- I use a thick, absorbent (and clean!) dish towel and squeeze the water out of the noodles, hard. The towel should be damp when done. I then lay the zucchini noodles out on a paper towel lined baking sheet or bowl until I’m ready to use them.
Don’t add in the zucchini noodles to the dish until you are ready to serve. If you’re meal prepping, you can place the chicken/veggie mixture into a container and place your raw zucchini noodles on top. When you’re ready to eat, microwave or heat over the stove to avoid mushy noodles.
We hope you love this hearty, delicious meal! It’s one of our favorites and is always a hit when served to family/friends.
How to store chicken tomato sauce:
This sauce actually gets better as the days go on and the flavors have time to meld together. This bolognese sauce can be stored in the refrigerator for up to 4 days, or you can freeze it in an air tight container.
If you freeze this sauce, when you’re ready to reheat, simply defrost it the night before and warm it on the stovetop.

Jen says
Made this today and it was amazing and my picky kids loved it! I added carrots and zucchini and zipped them in the food processor before adding in. I also did this in the instant pot…I browned the chicken first like the recipe states then cooked everything on high pressure for 7 mins and natural released then left it on slow cooker (only because I don’t have a separate slow cooker any more and sometimes the instant pot slow cook setting isn’t great imo). Turned out just like I anticipated! Super easy also which is great since I have 2 kiddos plus a newborn.

So glad you liked it, Jen! This makes me so happy to hear!

How many ounces of canned crushed tomatoes do you use? Is it two 28oz cans? When you double the serving size it says to use 60oz. Is that correct?
The Clean Eating Couple says
The recipe calls for 2 28 oz cans of crushed tomatoes. If you are going to double it, use 4!
