- Substitutions: Avocado oil, vegetable oil, or butter.

For the Topping:

Grated Parmesan Cheese (1 cup):

Step-by-Step Instructions

Making Slow Cooker Longhorn Steakhouse Parmesan Chicken requires a few prep steps for the crispy coating, but the slow cooker simplifies the cooking process. Follow these steps for a delicious result.

Step 1: Prepare the Breading Station

Pat 4 boneless, skinless chicken breasts dry with paper towels.
Set up three shallow bowls:
- Bowl 1: ½ cup all-purpose flour.
- Bowl 2: 2 large eggs beaten with ¼ cup milk.
- Bowl 3: Mix 1 cup Italian-style breadcrumbs, ½ cup grated Parmesan (reserve the other ½ cup for topping), 1 tsp Italian seasoning, ½ tsp salt, and ¼ tsp black pepper.
Dredge each chicken breast in flour, shaking off excess, then dip in the egg mixture, and coat evenly with the breadcrumb mixture, pressing gently to adhere.
Tip: Press the breadcrumb mixture firmly onto the chicken for a thicker, crispier coating.

Step 2: Sear the Chicken

Heat 2 tbsp olive oil in a large skillet over medium heat.
Sear the breaded chicken breasts for 3–4 minutes per side until golden brown but not fully cooked through (the slow cooker will finish cooking).
Transfer the chicken to a plate and set aside.
Tip: Sear in batches to avoid overcrowding, which can prevent browning and make the coating soggy.

Step 3: Assemble in the Slow Cooker

Lightly grease the slow cooker insert with cooking spray or a thin layer of oil to prevent sticking.
Place the seared chicken breasts in a single layer in the slow cooker.
Pour ¼ cup chicken broth around (not over) the chicken to keep it moist without softening the crispy coating.
Tip: Elevate the chicken slightly on a small rack or crumpled foil balls to maintain the coating’s texture, if desired.

Step 4: Cook

Cover and cook on low for 4–5 hours or high for 2–3 hours, until the chicken is fully cooked (165°F/74°C internally) and tender.
Check doneness at the lower end of the time to avoid overcooking, as slow cookers vary.
Tip: Avoid lifting the lid during cooking to maintain consistent heat and prevent moisture buildup.

Step 5: Add Cheese Topping

In a small bowl, mix 1 cup shredded mozzarella, the remaining ½ cup grated Parmesan, and 2 minced garlic cloves.
In the last 15–20 minutes of cooking, sprinkle the cheese mixture evenly over the chicken.
Cover and cook until the cheese is melted and bubbly.
Tip: For a golden, bubbly cheese topping, transfer the chicken to a baking dish and broil at 400°F (200°C) for 2–3 minutes after slow cooking (optional).

Step 6: Serve

Carefully transfer the chicken to plates, ensuring the cheese topping stays intact.
Garnish with 2 tbsp chopped fresh parsley for a vibrant finish.
Serve hot with sides like mashed potatoes, roasted asparagus, or a house salad.
Tip: Warm plates slightly to keep the dish hot, and serve with a side of dinner rolls to soak up any cheesy juices.

Assembly

Assembling Slow Cooker Longhorn Steakhouse Parmesan Chicken is all about creating a rich, restaurant-style plate. Here’s how to bring it together:

Serve the Chicken: Place one chicken breast per plate, showcasing the golden breadcrumb coating and melty cheese topping.
Garnish: Sprinkle with chopped parsley for a pop of color and freshness.
Presentation Tips:
- Use wide, white, or rustic plates to highlight the cheesy topping and golden crust.
- Arrange chicken neatly with the cheese side up for a polished look, or serve family-style in a large dish for a cozy vibe.
- Pair with garlic mashed potatoes, sautéed green beans, or a Caesar salad for a complete Longhorn Steakhouse-inspired meal, perfect for Valentine’s Day.

Tip: For a romantic touch, serve with a candlelit table setting or garnish with a heart-shaped sprinkle of parsley for Valentine’s Day.

Storage and Make-Ahead Tips

Keep your Slow Cooker Longhorn Steakhouse Parmesan Chicken fresh and ready to enjoy with these tips:

Storing Leftovers:
- Store cooled chicken in an airtight container in the fridge for up to 3–4 days.
- Reheating: Reheat in an oven or air fryer at 350°F (175°C) for 5–7 minutes to restore crispiness, or in the microwave (1–2 minutes, covered) for softness. Add a splash of broth if needed.
Make-Ahead Tips:
- Breading: Bread the chicken up to 1 day ahead, store in the fridge on a lined tray, and sear just before slow cooking.
- Cheese Topping: Mix the cheese and garlic topping up to 2 days ahead and refrigerate.
- Assembly: Sear breaded chicken and place in the slow cooker insert with broth the night before, cover, and refrigerate. Add cheese topping during cooking.
- Full Dish: Cook the chicken (without cheese) a day ahead, refrigerate, and reheat in the slow cooker on low for 1–2 hours, adding cheese in the last 15 minutes.
Freezing: Freeze breaded, seared (but uncooked) chicken in a single layer on a tray, then transfer to a freezer-safe bag for up to 2 months. Thaw in the fridge overnight, then slow cook as directed. Freeze cheese topping separately.

Tip: Use leftovers in sandwiches, salads, or a cheesy pasta bake for versatile meals.

Spicy Kick: Add ½ tsp red pepper flakes or cayenne to the breadcrumb mixture for a spicy crust.
