Ingredients

Scale

Meat and Vegetables

  • 1 lb lean ground beef (90/10 or 93/7)
  • 1 medium yellow onion, diced
  • 3 cups diced mushrooms (8 oz package)
  • 1 (12-ounce) bag frozen mixed vegetables
  • 1 cup frozen cauliflower rice
  • 1 (15-ounce) can cooked lentils (or 2 cups cooked lentils)

Sauce and Seasoning

  • 3 teaspoons avocado oil, divided
  • ¼ cup + 1 tablespoon all-purpose flour (use gluten-free flour if needed)
  • 3 cups low-sodium chicken broth or beef broth
  • ½ teaspoon fine salt
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ¼ teaspoon black pepper

Toppings

  • 1 ½ cups shredded cheddar cheese, divided
  • 1 (28-ounce) package frozen tater tots or crispy crowns

Instructions

  1. Preheat and Prepare: Preheat your oven to 400°F (200°C). Lightly mist a 9×13-inch baking dish with cooking spray and set aside to prepare for layering the casserole ingredients.
  2. Sauté Onions and Brown Beef: Heat 1 teaspoon of avocado oil in a skillet over medium-high heat. Add diced onion and sauté for about 2 minutes until slightly softened. Add ground beef, breaking it into small pieces as it cooks. Continue until fully browned, about 8-10 minutes.
  3. Drain Excess Fat and Assemble Beef Layer: If excess liquid or fat is present, drain it off. Transfer the cooked beef and onions to the prepared baking dish as the first casserole layer.
  4. Cook Mushrooms and Make Sauce: In the same skillet, add remaining 2 teaspoons avocado oil. Add diced mushrooms and cook over medium heat for 2-4 minutes until softened. Sprinkle the flour over mushrooms and stir well to coat evenly.
  5. Add Broth and Seasonings: Gradually pour in broth one cup at a time, stirring constantly to prevent lumps. Simmer for 3-5 minutes until thickened. Add salt, garlic powder, onion powder, and black pepper, stirring thoroughly.
  6. Combine Mixture and Layer: Pour mushroom sauce over beef mixture in the baking dish. Add cooked lentils, frozen mixed vegetables, frozen cauliflower rice, and 1 cup shredded cheddar cheese. Stir everything well and spread evenly.
  7. Top with Tater Tots and Cheese: Arrange frozen tater tots in an even layer on top of the casserole mixture, pressing lightly to help them stick. Sprinkle remaining ½ cup shredded cheddar cheese evenly over tater tots.
  8. Bake: Place casserole in preheated oven and bake 35-40 minutes, or until bubbly and tater tots are golden brown and crispy.
  9. Cool and Serve: Remove casserole from oven and allow to cool 5 minutes before serving to let flavors set and ensure easier portioning.
