Ingredients
  

Main Ingredients
  • 1 lb ground beef (80/20 blend) For the best flavor and texture
  • 2 cups green beans (trimmed, fresh or thawed frozen) Ensure they are crisp-tender
  • 1 cup diced onion (yellow or white)
  • 1 cup sliced button or baby bella mushrooms
  • 3 tsp minced garlic (fresh)
  • ¼ cup low-sodium beef or chicken broth
  • cup full-fat sour cream
  • 2 Tbsp cream cheese (room temperature)
  • ½ tsp sea salt (or to taste)
  • ½ tsp freshly ground black pepper
  • ½ tsp Worcestershire sauce
  • tsp dried thyme
  • 2 cups shredded Colby Jack cheese Use 1 cup for a lighter version

Method
 

Preparation
  1. Heat a large skillet over medium heat. Add the ground beef and cook for about 5 minutes, breaking it up until there's no pink left. Drain, saving a tablespoon of the fat, and set the beef aside.
  2. In the reserved fat, toss in the diced onions and let them cook for 3-4 minutes until they're nice and translucent. Add mushrooms next, and sauté for another 2 minutes.
  3. Stir in the green beans, minced garlic, and broth. Cook for about 2-3 minutes until the beans are bright green and still crisp.
  4. Turn the heat down to medium-low. Melt in the cream cheese and mix it until smooth. Blend in the sour cream to create a creamy sauce.
  5. Return the cooked beef to the skillet. Add sea salt, black pepper, Worcestershire sauce, and thyme. Stir gently until well coated.
Topping
  1. Sprinkle the shredded Colby Jack cheese evenly over the top.
Melting Cheese & Serving
  1. Option A: Pop the skillet under the broiler for 1-2 minutes until the cheese gets golden and bubbly.
  2. Option B: Cover and cook on low for 3-4 minutes until the cheese melts perfectly.

Notes

Pair this casserole with crusty bread or a light salad. Leftovers can be reheated in the microwave or skillet with a splash of broth to avoid dryness.
