Step-by-step overview
This is a no-fuss slow-cooker braise. You’ll season chicken breasts, nestle them in marinara, slow-cook until tender, then add the cheeses for the final melt. Total hands-on time is about 10 minutes; cooking time is 3–7 hours depending on the heat setting. Expect fork-tender meat that shreds slightly and soaks up sauce — perfect over pasta or with a crusty loaf.
Ingredient list
Gather these items:
- 4 boneless, skinless chicken breasts
- 1 cup marinara sauce (use your favorite jarred sauce or homemade)
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1 teaspoon Italian seasoning
- 1 teaspoon garlic powder
- Salt and pepper to taste
- Fresh basil for garnish (optional)
Substitution and notes:
- Chicken: thighs can be used instead of breasts for more fat and richness; reduce cooking time slightly if small pieces.
- Sauce: a robust marinara works best — a thin sauce can be thickened with a teaspoon of tomato paste.
- Cheese: fresh grated Parmesan (not powdered) gives better flavor and texture.
- For a lower-sodium dish, choose a low-sodium marinara and cut back on added salt.
Directions to follow
- Place the chicken breasts in the bottom of your slow cooker in a single layer. Pat them dry first so seasonings stick.
- Sprinkle the Italian seasoning, garlic powder, salt, and pepper evenly over the chicken.
- Pour the marinara sauce over the seasoned chicken, making sure each piece is covered or well-coated.
- Cover and cook on LOW for 6–7 hours or on HIGH for 3–4 hours, until the chicken reaches 165°F (74°C) with an instant-read thermometer and is tender.
- During the last 30 minutes of cooking, sprinkle the shredded mozzarella and grated Parmesan over the chicken. Replace the lid and allow the cheese to melt fully.
- Serve the chicken hot, spooning extra sauce over top and garnish with fresh basil if desired.
Quick safety tip: always verify doneness with an instant-read thermometer in the thickest part of the breast (165°F safe minimum).
What to serve with
Best ways to enjoy it:
- Over cooked spaghetti, linguine, or quick garlic buttered noodles for classic Chicken Parmesan.
- With a side of roasted vegetables (broccoli, asparagus, or a green salad) to balance the richness.
- On toasted ciabatta or a hoagie roll for an easy chicken parm sandwich.
- For a simple, comforting pairing, serve with creamy mashed potatoes or polenta.

Storage and reheating tips
Storing:
- Refrigerate leftovers within 2 hours in an airtight container. Keep for 3–4 days.
- To freeze, place cooled portions in freezer-safe containers or heavy-duty freezer bags for up to 3 months. Label with date.
Reheating:
- Thawed or refrigerated portions reheat well in a 350°F oven covered for 15–20 minutes, until hot. For single servings, microwave 1–2 minutes, stirring halfway through, until warmed to 165°F.
- If frozen solid, thaw overnight in the fridge before reheating for best texture.
Food safety note: Always reheat to an internal temperature of 165°F (74°C). Do not refreeze once thawed unless cooked again.
Helpful cooking tips
- Equal thickness: Pound thicker ends of chicken to an even thickness so all breasts cook uniformly.
- Don’t overdo liquids: One cup of marinara is enough. Too much sauce can water down flavor.
- Timing the cheese: Add cheese in the last 30 minutes to prevent it from becoming stringy or burning to the lid.
- Flavor boost: Sprinkle a pinch of red pepper flakes into the sauce if you like a little heat.
- Make it weeknight-ready: Trim and season chicken the night before and store covered in the fridge; in the morning, add to the slow cooker with sauce.

Creative twists
Recipe variations to try:
- Italian herb crust: Mix 1/2 cup breadcrumbs with 2 tablespoons melted butter and a tablespoon chopped parsley, sprinkle on top with the cheeses before the last 30 minutes for a crisp topping.
- Low-carb: Skip the pasta and serve over zoodles or cauliflower mash.
- Spicy tomato: Stir in a tablespoon of harissa or a few tablespoons of arrabbiata sauce into the marinara.
- Keto-friendly: Use full-fat cheeses and serve with roasted cauliflower.
- Make it saucy: Add a splash of balsamic or a teaspoon of sugar to the marinara for a deeper, sweeter sauce.
Common questions
Q: Can I use frozen chicken breasts?
A: It’s safest to use thawed chicken in slow cookers. Cooking frozen chicken in a slow cooker can keep it in the temperature danger zone too long. Thaw overnight in the fridge before starting.
Q: Can I brown the chicken before adding to the slow cooker?
A: Yes. Searing chicken briefly in a hot skillet adds flavor and color, but it’s optional. The slow cooker will still produce tender results without browning.
Q: How do I prevent the chicken from drying out?
A: Avoid overcooking — check at the shorter end of the time range. Using breasts of similar size and ensuring they’re at least partly covered by sauce helps retain moisture.
Q: Can I double the recipe?
A: Yes. Use a larger slow cooker and keep similar cook times, though very full slow cookers may need a little extra cooking time. Make sure pieces aren’t stacked too tightly.
Q: Is this recipe freezer-friendly after cooking?
A: Yes. Cool completely, then freeze in airtight containers up to 3 months. Thaw overnight before reheating.
