Cooking Instructions
1. Prepare the Chicken
Place the raw chicken breasts into the bottom of the slow cooker insert. Ensure they are in a relatively even layer so they cook consistently. Season both sides of the chicken lightly with salt and black pepper.
2. Layer the Flavors
Sprinkle the minced garlic, dried Italian seasoning, and crushed red pepper flakes directly over the chicken. Evenly distribute the grated Parmesan cheese over the top of the spices.
3. Add the Marinara
Pour the entire jar of marinara sauce over the chicken, making sure all the pieces are well-covered. This moisture is essential for keeping the lean chicken breasts from drying out during the long cook time.
4. Slow Cook to Perfection
Cover the slow cooker with the lid. Cook on Low for 4 to 6 hours or on High for 2 to 3 hours. The chicken is done when it reaches an internal temperature of 165°F and is easily pierced with a fork.
5. Shred and Serve
Once cooked, you can serve the chicken breasts whole or use two forks to shred the meat directly in the slow cooker, allowing it to soak up even more of the infused marinara sauce.
Expert Tips for Success
Choosing the Best Sauce
Since the marinara is the primary flavor component, choose a sauce that has a robust profile. Look for jars that list extra virgin olive oil and whole peeled tomatoes as the first ingredients for the most authentic taste.
Managing Moisture
Chicken breasts release liquid as they cook. If you prefer a thicker sauce, you can stir in a small amount of tomato paste during the last 30 minutes of cooking, or leave the lid slightly ajar for the final half-hour to allow some steam to escape.
Adding a Fresh Finish
Right before serving, stir in a handful of fresh chopped basil or parsley. The brightness of fresh herbs cuts through the rich, slow-cooked sauce and adds a professional touch to the final presentation.
Serving Suggestions and Variations
Classic Italian Style
Serve the shredded marinara chicken over a bed of al dente spaghetti or penne. Top with an extra sprinkle of Parmesan and a side of buttery garlic bread for a comforting meal.
Low-Carb Options
For a lighter alternative, serve the chicken over roasted spaghetti squash, zoodles (zucchini noodles), or a bed of sautéed spinach. The bold sauce provides plenty of flavor without the need for traditional pasta.
The Marinara Melt
Place the cooked chicken inside toasted hoagie rolls, top with a slice of provolone or mozzarella cheese, and place under the broiler for 1-2 minutes until the cheese is bubbly and golden brown.
Storage and Reheating
This recipe is excellent for meal prep. Store leftovers in an airtight container in the refrigerator for up to 4 days. When reheating, add a splash of water or extra sauce to maintain the moisture of the chicken.
