Ingredients
  

  • 1 lb ground beef
  • 2 teaspoon garlic cloves minced
  • 1 cup onion diced
  • 3 cups sliced zucchini
  • ¼ cup beef or chicken broth
  • ⅓ cup sour cream
  • 2 tablespoon cream cheese
  • ½ teaspoon sea salt
  • ½ teaspoon ground black pepper
  • 1 teaspoon Worcestershire sauce or coconut aminos for GF
  • 1.5 cups shredded cheddar cheese

Instructions
 

  • In a cast-iron skillet, cook the ground beef on medium heat until browned, about 5 minutes. Remove ground beef and drain grease, leaving 1 tablespoon of the grease in the pan to saute the vegetables in.
  • In the same skillet, cook the chopped onions over medium heat until they start to soften, about 3 minutes. Add the garlic to the pan and cook for 1 more minute.
  • Add the zucchini and broth to the pan and cook until the zucchini is soft, about 5 more minutes.
  • Turn the heat down to medium-low add the cream cheese and then sour cream. Add the beef back into the pan along with the salt, pepper, and Worcestershire sauce. Stir gently to combine.
  • Sprinkle cheddar cheese over the top.
  • Place the entire dish in the oven and broil for 2 minutes until the cheese is browned and melted. Or, add lid to skillet and cook for 3-4 minutes until the cheese melts. Using the stovetop, your cheddar cheese won't be crispy, but it will melt.

Notes

  • If you don't have a cast-iron skillet or other oven-safe skillet be sure to transfer the casserole to an oven-safe baking dish before broiling.
  • Make this lower carb: reduce the zucchini or onion and use full-fat sour cream and cream cheese.
  • This is a very cheesy casserole! You can totally reduce the cheddar cheese or swap some of the full fat dairy products for lower fat.
