Creamy Crockpot High Protein Chicken Pasta
Ditch dry meal prep chicken breasts. This viral slow cooker pasta recipe is packed with shredded chicken, robust marinara, rich Alfredo, and gooey mozzarella for ultimate satisfaction.
Ingredients
1.5 lbs boneless, skinless chicken breasts (2-3 large breasts)
24 oz high-quality jarred marinara sauce (1 jar)
15 oz rich garlic Alfredo sauce (1 jar)
8 oz sturdy low-carb or high-protein pasta (like rotini or penne)
1 cup low-moisture mozzarella cheese (shredded from a block)
½ large yellow onion (finely diced)
1 tbsp dried Italian seasoning
1 tsp garlic powder
½ tsp fine sea salt
½ tsp freshly cracked black pepper
¼ cup fresh basil leaves (finely chopped for garnish)
Instructions
Fine-dice your yellow onion and scatter the pieces evenly across the bottom of your slow cooker insert. Lay the raw chicken breasts flat in a single layer directly over the onion bed.
Dust your garlic powder, dried Italian seasoning, sea salt, and black pepper directly over the chicken meat. Pour the entire jar of marinara and Alfredo sauce over the top, smoothing it out to submerge the meat completely.
Lock the slow cooker lid in place. Program the machine to cook on LOW for 5 to 6 hours (or on HIGH for 3 to 4 hours) until the chicken breasts are completely tender and pull apart easily.
Use tongs to lift the chicken out onto a cutting board. Shred the breasts using two forks, then slide the shredded meat straight back into the warm sauce pool, stirring thoroughly to combine.
While the chicken is being shredded, bring a pot of salted water to a boil on your stove. Cook your low-carb pasta for 1 to 2 minutes less than the box instructions state for al dente, then drain completely.
Dump the hot, drained pasta and your shredded mozzarella cheese directly into the slow cooker basin. Fold everything together gently for 1 minute until gooey and melted. Garnish with fresh basil and serve.
Notes
The Low-Heat Rule: Always prioritize cooking this dish on the LOW setting if your schedule allows. High heat can cause the dairy components inside the Alfredo sauce to separate from the tomato fats, turning your smooth sauce oily. Never Cook Raw Pasta in the Sauce: Boiling your pasta separately on the stove is a non-negotiable step. Cooking dry noodles directly in the crockpot absorbs all the loose liquid and leaves you with a gummy, starch-heavy texture. Grate Your Own Cheese: Avoid buying pre-bagged shredded mozzarella. Those products are coated in anti-clumping starches that prevent the cheese from melting into smooth, velvety strands when folded into the hot pasta. Intentionally Undercook the Noodles: Because the hot pasta will continue to cook and soften inside the residual heat of the slow cooker sauce, draining it when it still has a firm snap ensures it stays perfectly al dente. Easy Reheating Fix: Leftover pasta will naturally soak up extra sauce as it sits in the fridge overnight. When reheating your lunch portion on the stove, simply stir in a splash of milk or water to instantly restore the creamy texture.
