4.8 from 83 reviews

A rich and creamy Keto Beef and Mushroom Casserole, perfect for low-carb diets. This hearty dish combines ground beef, mushrooms, and a savory blend of cream and cheddar cheese baked to bubbly perfection.

Ingredients

Scale

Beef Mixture

  • 1 pound ground beef
  • 2 cups sliced mushrooms
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 1 teaspoon thyme
  • 1/2 cup beef broth
  • 1 cup heavy cream
  • Salt and pepper to taste
  • Olive oil for cooking

Topping

  • 1 cup shredded cheddar cheese

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
  2. Sauté Aromatics: In a large skillet, heat olive oil over medium heat. Add diced onion and minced garlic, cooking until softened and fragrant, about 3-4 minutes.
  3. Cook Beef: Add ground beef to the skillet and cook until browned, breaking it apart as it cooks. Drain excess fat to keep the casserole from becoming greasy.
  4. Add Mushrooms and Liquids: Stir in sliced mushrooms, beef broth, heavy cream, thyme, salt, and pepper. Cook the mixture for 5-7 minutes, allowing the mushrooms to soften and the flavors to blend.
  5. Assemble Casserole: Transfer the beef and mushroom mixture into a greased 9×9-inch baking dish. Evenly sprinkle the shredded cheddar cheese on top.
  6. Bake: Place the dish in the preheated oven and bake for 20-25 minutes, until the cheese melts and becomes bubbly and golden.
  7. Rest and Serve: Remove from oven and let the casserole cool slightly before serving to allow it to set.

Notes

  • For a creamier texture, use full-fat heavy cream.
  • Feel free to substitute cheddar with Monterey Jack or mozzarella for a different flavor.
  • To make this dish dairy-free, consider using coconut cream and a vegan cheese alternative.
  • Adjust seasoning according to taste before baking.
  • This casserole can be prepared ahead of time and refrigerated before baking.
