There are days when cooking feels like one more thing on an already overwhelming to-do list. Between work deadlines, family schedules, and trying to eat a little healthier, the idea of making a homemade dinner can feel impossible. That’s exactly why I started leaning into slow cooker meals that require almost no effort but still feel comforting and nourishing.
This crockpot tomato chicken recipe came from one of those busy weeks when my fridge looked nearly empty and I needed something simple that could stretch across several meals. I tossed a pack of chicken thighs into the slow cooker with a jar of tomato sauce, crossed my fingers, and hoped for the best. Hours later, the house smelled incredible, and dinner practically served itself.
What surprised me most was how versatile it turned out to be. The chicken became tender enough to shred with a fork, and the tomato base transformed into a rich, savory sauce that worked over rice, pasta, or even roasted vegetables. It quickly became one of my favorite easy meal prep recipes.
Now it’s a regular in my weekly rotation because it checks all the boxes: minimal prep, high-protein dinner, budget-friendly ingredients, and leftovers that actually taste better the next day.

Pro Cooking Tips and Ingredient Substitutions
Even though this recipe is famously simple, a few small tweaks can make a big difference in flavor and texture.
Choose bone-in or boneless chicken thighs based on your preference. Bone-in thighs tend to stay juicier and richer, while boneless thighs shred more easily for meal prep bowls or wraps.
If you want a deeper flavor, sear the chicken briefly in a hot pan before placing it into the crockpot. This step isn’t required, but it adds a slightly roasted taste that some people love.
Not a fan of jarred tomato sauce? Crushed tomatoes, passata, or even salsa can work. Just be sure the sauce isn’t overly watery; a thicker base helps keep the chicken flavorful rather than diluted.
Seasoning is optional but welcome. Garlic powder, Italian herbs, smoked paprika, or a pinch of chili flakes can elevate the dish without complicating the ingredient list.
And if you’re cooking for kids or sensitive eaters, choose a mild tomato sauce without too much acidity or spice. A smoother sauce creates a more comforting, universally appealing result.
Calories and Nutrition Overview
One of the reasons this recipe has become so popular is that it fits easily into many eating styles without needing major adjustments.
Chicken thighs are naturally rich in protein, making this an excellent high-protein dinner that keeps you full longer. Depending on the tomato sauce you choose, the dish can also be relatively low in carbohydrates, especially when served with vegetables instead of pasta or bread.
A typical serving provides a strong balance of protein and healthy fats while remaining satisfying enough to prevent unnecessary snacking later. If you’re following a lower-carb or high-protein lifestyle, this recipe adapts beautifully without sacrificing flavor.
To keep calories lighter, choose a tomato sauce with no added sugar and trim excess fat from the chicken thighs before cooking. Pairing it with roasted zucchini, cauliflower rice, or a simple salad creates a well-rounded, nutrient-dense meal.
Kitchen Tools You’ll Need
- Slow cooker or crockpot (4–6 quart works well)
- Slow cooker liners for easier cleanup
- Kitchen tongs for handling the chicken
- Forks for shredding
- Optional air fryer if you want to crisp the chicken after slow cooking
Ingredients
- 6–8 chicken thighs (boneless or bone-in)
- 2 cups tomato sauce or marinara
Optional add-ons:
- Garlic powder
- Italian seasoning
- Salt and black pepper
- Chili flakes for a little heat
Step-by-Step Crockpot Cooking Instructions
Start by lightly greasing your slow cooker or using a liner. This makes cleanup much easier later, especially if you’re meal prepping for the week.
Place the chicken thighs in an even layer at the bottom of the crockpot. Try not to stack them too tightly, as even spacing helps them cook more evenly.
Pour the tomato sauce over the chicken, making sure each piece is coated. If you’re adding optional seasoning, sprinkle it over the top now.
Cover with the lid and cook on LOW for 6–7 hours or HIGH for about 3–4 hours. Cooking on low tends to produce the most tender texture, especially for shredding.
Once the chicken is fully cooked, use tongs to gently move the pieces around so they soak up the sauce. At this point, you can leave the thighs whole or shred them with two forks directly in the crockpot.
If you prefer slightly crispy edges, transfer the cooked chicken to an air fryer for a few minutes before serving. This creates a delicious contrast between the tender inside and lightly crisp exterior.
Serve hot over rice, mashed potatoes, pasta, or roasted vegetables depending on your preferences.
Variations
Keto Version
To make this recipe keto-friendly, choose a tomato sauce without added sugar and keep the seasoning simple. Serve the chicken over cauliflower rice or sautéed spinach instead of traditional grains.
Low-Carb Version
For a low-carb dinner, pair the chicken with roasted broccoli, zucchini noodles, or a fresh green salad. The sauce adds plenty of flavor, so you won’t miss heavier sides.
High-Protein Version
If your goal is maximizing protein, use skinless boneless thighs or even a mix of thighs and chicken breasts. Shred the meat and portion it into meal prep containers with steamed vegetables for an easy high-protein lunch throughout the week.
Vegetable Add-Ins
This recipe is also a great way to use up vegetables you already have. Bell peppers, mushrooms, onions, or spinach can be added during the last hour of cooking. Root vegetables like carrots or potatoes can go in at the beginning since they need more time to soften.
Storage, Freezer, and Meal Prep Tips
One of the best things about this crockpot chicken is how well it stores. Once cooled, transfer leftovers into airtight containers and refrigerate for up to four days. The flavor often deepens overnight, making it perfect for next-day lunches.
For freezer storage, portion the cooked chicken and sauce into freezer-safe bags or containers. Lay bags flat to save space and make thawing faster. It can be frozen for up to three months.
When reheating, add a splash of water or broth if the sauce has thickened too much. Warm it gently on the stove or in the microwave to prevent the chicken from drying out.
If you’re planning easy meal prep, divide the chicken into individual containers with vegetables or grains so you can grab a complete meal during busy weekdays.
Frequently Asked Questions
Can I use frozen chicken thighs in the crockpot?
For food safety, it’s best to thaw chicken first. Starting with fully thawed meat ensures even cooking and helps the chicken reach a safe internal temperature more quickly.
Do I need to add extra liquid?
Usually, no. Chicken releases its own juices as it cooks, and the tomato sauce provides enough moisture. Adding extra water can make the sauce too thin.
How do I make the sauce thicker?
If the sauce seems watery at the end of cooking, remove the lid and cook on HIGH for another 20–30 minutes. You can also shred the chicken and let it simmer uncovered so the sauce reduces naturally.
Can I make this recipe spicy?
Absolutely. Add chili flakes, cayenne pepper, or a spicy marinara sauce to bring more heat. Adjust gradually so you don’t overpower the dish.
What’s the best way to serve this chicken?
It’s incredibly versatile. Serve it over pasta for a comforting dinner, tuck it into wraps, pile it onto baked potatoes, or use it as a topping for grain bowls and salads.
A Friendly Final Note
Simple recipes like this remind me that good food doesn’t have to be complicated to feel satisfying. Some of the most comforting meals come from a handful of ingredients and a little patience while the slow cooker does its thing. Whether you’re feeding a family, prepping lunches for the week, or just trying to make dinner easier, this high-protein crockpot chicken has a way of fitting into real life without stress.
If you try it, don’t be afraid to make it your own. Add your favorite spices, toss in extra vegetables, or crisp it up in the air fryer for a different texture. Cooking at home should feel flexible and forgiving, and recipes like this are a reminder that sometimes the simplest dishes are the ones you come back to again and again.
