What You’ll Need
To keep this a true 6-ingredient recipe, we aren’t counting the basic pinch of salt or the cooking spray!
- 1 ½ to 2 lbs Boneless, skinless chicken breasts: (About 3 to 4 medium breasts).
- 1 jar (24 oz) Store-bought marinara sauce: Grab a high-quality brand, as this makes up the bulk of your flavor!
- 1 tsp Garlic powder.
- 1 tsp Dried Italian seasoning: (Or dried oregano).
- 1 ½ cups Mozzarella cheese: Shredded.
- ¼ cup Parmesan cheese: Grated.
- Pantry Staples: ½ tsp kosher salt (or to taste) and nonstick cooking spray.
How to Make It (Step-by-Step)
Prep time: 5 minutes | Cook time: 2.5–5 hours | Total time: approx. 3–5 hours | Yield: 4 Servings
Step 1: Prep the Crock
Spray the inside of your slow cooker with nonstick cooking spray (or lightly grease it with a bit of olive oil) to make cleanup a breeze.
Step 2: The Chicken Base
Lay the raw chicken breasts in a single layer on the bottom of the slow cooker. It’s totally okay if they overlap a little bit, but try to keep them mostly flat so they cook evenly!
Step 3: Season the Sauce
In a medium bowl, pour in the entire jar of marinara sauce. Stir in the garlic powder, dried Italian seasoning, and kosher salt until everything is beautifully combined.
Step 4: The Pour-Over
Pour the seasoned marinara sauce evenly over the raw chicken breasts in the slow cooker, making absolutely sure all of the meat is submerged and covered in the sauce.
Step 5: Low and Slow
Cover the slow cooker tightly with the lid. Cook on LOW for 4 to 5 hours, or on HIGH for 2 ½ to 3 hours, until the chicken is cooked completely through and easily shreds with a fork.
Step 6: Shred the Meat
💡 Crucial Step: Once the chicken is done, use two forks to gently shred and break apart the chicken breasts right in the slow cooker! Mix the shredded meat heavily into the hot marinara sauce so everything is thoroughly coated. (Note: If you prefer whole chicken breasts, you can completely skip the shredding step!)
Step 7: The Cheesy Finish
Sprinkle the shredded mozzarella cheese evenly over the top of the saucy chicken, then sprinkle the grated Parmesan cheese directly over the mozzarella.
Step 8: Melt and Serve
Cover the slow cooker again and cook on LOW for an additional 10 to 15 minutes, or until the cheese is completely melted and gooey. Serve hot and enjoy!
💡 Expert Tips for Success
- Freshly Grate the Cheese: Pre-packaged shredded mozzarella is coated in anti-caking powders that prevent it from melting smoothly. For that incredibly gooey, restaurant-quality cheese pull, grate your mozzarella fresh from the block!
- Keep it Warm: If your slow cooker has a “Warm” setting, you can switch it over the exact second the cheese is melted, and hold it there until your family is ready to eat.
Variations and Substitutions
- The “Classic Casserole” Feel: To make this taste even more like a classic, breaded chicken parmesan, stir ½ cup of toasted, seasoned breadcrumbs into the sauce right after shredding the chicken, but before you add the cheese!
- Sneak in Some Veggies: Add a small sliced onion or a handful of fresh, sliced button mushrooms underneath the chicken before pouring on the marinara to effortlessly stretch the meal.
- The Spicy Arrabbiata: If you like a little heat with your Italian food, sprinkle ¼ teaspoon of crushed red pepper flakes into the marinara sauce along with the garlic powder!
Serving Suggestions
- The Starchy Base: Spoon this rich, saucy chicken over a massive bowl of hot spaghetti, penne, or buttered egg noodles to soak up the marinara.
- The Lighter Option: If you are trying to keep things low-carb, this chicken is absolutely phenomenal served over a bed of roasted spaghetti squash, zucchini noodles, or steamed broccoli!
- The Chicken Parm Sandwich: Leftovers make the most amazing chicken parmesan-style sandwich! Pile the shredded chicken and extra sauce onto a toasted hoagie roll, top with a little more cheese, and pop it under the broiler until perfectly melty.
Frequently Asked Questions (FAQs)
Can I use frozen chicken breasts?
For food safety reasons, it is highly recommended to completely thaw your chicken before putting it in the slow cooker. Cooking frozen chicken in a crockpot can keep the meat in the temperature “danger zone” for too long, allowing bacteria to grow.
How do I store and reheat leftovers?
Store the cheesy chicken and sauce in an airtight container in the refrigerator for up to 4 days. It meal-preps incredibly well! Just portion it out into containers with cooked pasta or rice for grab-and-go lunches that reheat beautifully in the microwave.
