Ingredients for High Protein Crockpot Marry Me Chicken
I have made this recipe more times than I can count, and every ingredient here earns its place. The sauce is what makes this dish, so using the right ratios matters.
- 4 boneless skinless chicken breasts (6 to 8 oz each)
- 1 tsp kosher salt
- 1/4 tsp black pepper
- 1/4 tsp onion powder
- 1/2 tsp Italian seasoning
- 1 tsp olive oil
- 1 small shallot (finely chopped)
- 2 cloves garlic, crushed — I always use fresh garlic only; jarred garlic will make the sauce taste flat
- 1/4 cup chopped sun-dried tomatoes (not packed in oil) — Pro tip: dry-packed sun-dried tomatoes give a more concentrated flavor without excess grease
- 1 cup low-sodium chicken broth
- 1/2 tsp chili crunch oil or a pinch of red pepper flakes (optional)
- 2 tbsp cornstarch
- 2 tbsp water (for cornstarch slurry)
- 2 tbsp grated Parmesan cheese (freshly grated preferred)
- 1/2 cup blended cottage cheese (any fat content) — In my experience, blending the cottage cheese completely smooth before measuring is non-negotiable; skip this step and the sauce turns grainy
- 3 tbsp chopped fresh basil (for garnish)
Step-by-Step Instructions
In my experience, the sear before slow cooking is what takes this high protein crockpot marry me chicken from good to genuinely great. Do not skip it.
Step 1: Season chicken breasts evenly on both sides with kosher salt and black pepper. Set aside while you prepare the aromatics.
Step 2: Heat olive oil in a large skillet over medium-high heat. Add the finely chopped shallot and crushed garlic, sauteing for about 2 minutes until fragrant and softened. Watch carefully — garlic burns fast and turns bitter, which will affect the whole sauce.
Step 3: Push the aromatics to the side and add the seasoned chicken breasts. Sear for 2 to 3 minutes per side until golden brown on the outside. The chicken will not be cooked through at this stage. Sprinkle the onion powder and Italian seasoning over the chicken while it sears.
Step 4: Transfer the seared chicken and all pan drippings to the slow cooker, arranging in a single layer. Add the sun-dried tomatoes, chicken broth, and optional chili oil or red pepper flakes. Cover and cook on LOW for 4 to 6 hours until the chicken reaches an internal temperature of 165 degrees F in the thickest part.
Step 5: About 30 minutes before your target finish time, whisk together the cornstarch and 2 tablespoons of water until smooth. Stir this slurry into the sauce to help it thicken.
Step 6: Once cooking is complete, turn off the heat. Stir in the grated Parmesan and the fully blended cottage cheese until the sauce is silky smooth. If the sauce is too thick, add 2 to 3 tablespoons of chicken broth. Return the chicken to coat fully, let it rest for 5 minutes, then serve garnished with fresh chopped basil.
What to Serve with High Protein Crockpot Marry Me Chicken
The creamy, tangy sauce in this dish pairs best with sides that soak it up or balance the richness with freshness. Here are my favorite ways to complete the meal.
Cauliflower Rice: A light, low-carb base that soaks up every bit of that creamy sun-dried tomato sauce without weighing the meal down. It is my go-to pairing for keeping the macros clean.
Zucchini Noodles: Zucchini noodles add a fresh, light texture that contrasts beautifully with the rich sauce. They are a great option for anyone keeping the meal low in carbs. Try pairing this with my Easy Chicken Zucchini Bake if you love zucchini-based meals.
Simple Romaine Salad with Lemon Vinaigrette: The bright acidity of lemon cuts through the creaminess of the sauce and refreshes the palate between bites. A Chickpea Beet and Feta Salad also works wonderfully here for extra nutrition and color.
Roasted Asparagus: The slightly bitter, caramelized flavor of roasted asparagus is one of the best sides for this dish. It adds a nutritional boost and a satisfying texture contrast.
Garlic Green Beans: Crisp, garlicky green beans keep the meal feeling fresh and add fiber to round out the protein-heavy bowl.
Cottage Cheese Pasta for Extra Protein: If you love using cottage cheese to boost protein in your meals, my Cottage Cheese Protein Pasta Bake makes an incredible companion dish for a full high-protein dinner spread.
Storage and Serving Tips
Store leftovers in an airtight container in the refrigerator for up to 4 days. The sauce actually deepens in flavor overnight, which makes this high protein crockpot marry me chicken one of my favorite meal prep recipes. The cooked sauce also freezes well for up to 3 months.
To reheat, warm gently on the stovetop over low heat with a small splash of chicken broth if the sauce has thickened. You can also reheat in the microwave at 50 percent power, stirring halfway through to keep the sauce smooth and even.
I recommend storing the chicken and sauce together so the meat stays moist. If you enjoy creamy, protein-packed meals, my Cottage Cheese Mushroom Soup uses the same blended cottage cheese technique and is another great option to batch cook alongside this recipe.
FAQs
Can I use chicken thighs instead of chicken breasts?
Yes. Boneless skinless chicken thighs work well in this recipe and stay especially moist during slow cooking. The protein per serving will be slightly lower but the flavor is just as rich.
Why does my sauce look grainy?
This almost always happens when the cottage cheese was not blended completely smooth before being added. Blend it until it is fully silky, then stir it in off the heat for the best results.
Can I cook this on HIGH instead of LOW?
You can cook on HIGH for 2.5 to 3 hours if you are short on time. However, LOW heat produces a more tender chicken and a better-developed sauce. Always verify internal temperature reaches 165 degrees F regardless of setting.
Conclusion
This high protein crockpot marry me chicken is proof that a slow cooker dinner can be rich, satisfying, and genuinely impressive without hours of hands-on cooking. With 30 grams of protein per serving and a sauce that tastes like it came from a restaurant, this recipe earns its name. Give it a try this week and let the slow cooker do the work for you.
