Ingredients
Scale
Main Ingredients
- 1 lb ground beef (80/20 blend)
- 2 cups green beans (trimmed, fresh or thawed frozen)
- 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
Dairy & Seasonings
- ⅓ 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
- ⅛ tsp dried thyme
- 2 cups shredded Colby Jack cheese (use 1 cup for lighter version)
Instructions
- Brown the Beef: Heat a large cast-iron skillet over medium heat. Add ground beef and cook for about 5 minutes, breaking it up as it cooks until no pink remains. Drain excess fat, reserving 1 tablespoon of fat in the pan. Remove beef from pan and set aside.
- Sauté Aromatics: In the reserved fat, add diced onion and cook for 3 to 4 minutes until translucent. Add sliced mushrooms and sauté another 2 minutes until they begin to caramelize, enhancing their flavor.
- Add Beans & Seasonings: Stir in the trimmed green beans, minced garlic, and low-sodium broth. Cook for 2 to 3 minutes until the green beans turn a bright green color and are crisp-tender.
- Create Creamy Base: Reduce heat to medium-low. Add the cream cheese to the skillet and stir until melted and smooth. Then blend in the sour cream to form a creamy sauce coating the vegetables.
- Combine & Season: Return the cooked ground beef to the skillet. Add sea salt, pepper, Worcestershire sauce, and dried thyme. Stir gently to combine and ensure everything is evenly coated with the creamy sauce and seasonings.
- Cheese Topping: Evenly sprinkle the shredded Colby Jack cheese over the surface of the mixture in the skillet.
- Melt & Serve: Option A (Broiler): Place the skillet under the broiler for 1 to 2 minutes until the cheese is golden and bubbly. Option B (Stovetop): Cover the skillet and cook on low heat for 3 to 4 minutes until the cheese melts completely. Serve the casserole hot.
Notes
- Use fresh or thawed frozen green beans depending on availability.
- For a lighter version, reduce the amount of Colby Jack cheese to 1 cup.
- Reserving some fat from the beef adds rich flavor when sautéing the onions and mushrooms.
- Make sure to not overcook the green beans; they should stay crisp-tender for best texture.
- This dish can be prepared in a cast-iron or other oven-safe skillet for broiler finishing.
