Ingredients

  • 6 boneless chicken breasts
  • 3 beaten eggs
  • 2 cups bread crumbs
  • 1 teaspoon salt
  • 1 tablespoon parsley
  • 1/2 teaspoon garlic powder
  • vegetable oil
  • 8 ounces fresh mushrooms sliced
  • 6 slices Muenster cheese
  • 1 cup chicken broth

Instructions

  1. Marinate chicken in beaten eggs for 2 hours in the refrigerator.
  2. Combine bread crumbs, parsley, salt, and garlic powder in a plastic bag.
  3. Shake chicken in bread crumb mixture and brown in vegetable oil.
  4. Drain and place chicken in a 13 x 9 x 2-inch baking dish.
  5. Cover with sliced mushrooms and top with cheese slices.
  6. Pour chicken broth on top.
  7. Can be made ahead of time; pour broth on just before baking.
  8. Bake covered at 350°F for 30 minutes.

Tips & Substitutions

For a twist, try adding some grated Parmesan to the bread crumb mixture for extra flavor. If you don't have Muenster cheese, substitute with mozzarella or provolone. To cut down on prep time, use pre-sliced mushrooms or even frozen ones. Make sure to marinate the chicken well to enhance its juiciness, and consider doubling the recipe for larger gatherings.

Serving Suggestions

This casserole pairs beautifully with a fresh green salad or steamed vegetables like broccoli or green beans. For a heartier meal, serve it alongside a side of mashed potatoes or rice. Consider complementing it with a light sauce like a lemon butter or a balsamic reduction for an extra layer of flavor.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and bake at 350°F until warmed through, about 20-25 minutes. You can also microwave individual portions for quicker reheating, but the oven method helps retain the casserole's texture.

Frequently Asked Questions

Can I use frozen chicken breasts?

Yes, you can use frozen chicken breasts, but make sure to thaw them completely before marinating and cooking. This will help ensure even cooking and allow the flavors to penetrate the chicken better.

How can I make this dish gluten-free?

To make this casserole gluten-free, use gluten-free bread crumbs instead of regular ones. Additionally, ensure the chicken broth is gluten-free, or make your own broth to control the ingredients.

Can I prepare this casserole the night before?

Absolutely! You can assemble the casserole the night before, just be sure to cover it tightly and refrigerate. Add the chicken broth before baking to keep it moist. This makes for a convenient meal option for busy weeknights.
