How to Make Hamburger Green Bean Casserole with Mushrooms
Ready to dive in? You won’t believe how simple and quick this recipe is! Plus, it all comes together in one skillet. No one wants to do dishes after all that cooking, right? Here’s how you create this culinary masterpiece:
Brown the Beef: Heat a large skillet over medium heat. Add the ground beef and cook for about 5 minutes. Break it up until there’s no pink left. Drain, saving a tablespoon of the fat, and set the beef aside.
Sauté Aromatics: In the reserved fat, toss in the diced onions and let them cook for 3-4 minutes until they’re nice and translucent. Toss in the mushrooms next, and sauté for another 2 minutes for that yummy caramelization.
Add Beans & Seasonings: Now it’s green bean time! Stir in the green beans, minced garlic, and broth. Give it about 2-3 minutes until the beans are bright green and still crisp. 💚
Create Creamy Base: 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 that dreams are made of.
Combine & Season: Return the cooked beef to the skillet. Add the sea salt, black pepper, Worcestershire sauce, and thyme. Stir gently until everything is well coated.
Cheese Topping: Sprinkle that glorious Colby Jack cheese evenly over the top.
Melt & Serve:
- Option A (broiler): Pop the skillet under the broiler for 1-2 minutes until that cheese gets golden and bubbly.
- Option B (stovetop): Cover and cook on low for 3-4 minutes until the cheese melts perfectly. 🍽️
