Introduction
This Hamburger Green Bean Casserole with Mushrooms is a comforting one-pan meal that combines savory ground beef, tender green beans, and a creamy, cheesy sauce. With rich flavors from garlic, mushrooms, and Worcestershire sauce, it’s a hearty dish perfect for weeknights or cozy dinners.

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
- 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
- Step 1: Heat a large skillet over medium heat. Add the ground beef and cook for about 5 minutes, breaking it up with a spoon, until no pink remains. Drain excess fat, leaving 1 tablespoon of fat in the pan. Remove the beef and set aside.
- Step 2: In the reserved fat, add the diced onion and cook for 3 to 4 minutes until translucent. Add the sliced mushrooms and sauté for another 2 minutes until they start to caramelize.
- Step 3: Stir in the green beans, minced garlic, and broth. Cook for 2 to 3 minutes until the beans turn bright green and are crisp-tender.
- Step 4: Reduce the heat to medium-low. Add the cream cheese and stir until melted and smooth. Then blend in the sour cream to create a creamy sauce.
- Step 5: Return the cooked ground beef to the skillet. Add salt, pepper, Worcestershire sauce, and dried thyme. Stir gently to combine all ingredients evenly.
- Step 6: Sprinkle the shredded Colby Jack cheese evenly over the top of the mixture.
- Step 7: To melt the cheese, either place the skillet under the broiler for 1 to 2 minutes until the cheese is golden and bubbly, or cover and cook on low heat for 3 to 4 minutes on the stovetop until melted. Serve hot.
Tips & Variations
- For a lighter version, reduce the cheese to 1 cup or use reduced-fat sour cream and cream cheese.
- Fresh green beans provide the best texture, but frozen can work well if thawed and drained.
- Try adding a pinch of smoked paprika or chili flakes for a subtle kick.
- Use a cast-iron skillet if possible for even cooking and easy broiling.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm on the stovetop over low heat or in the microwave until heated through. Add a splash of broth if the casserole seems dry during reheating.

FAQs
Can I make this casserole ahead of time?
Yes, you can prepare the casserole up to the step before adding cheese and melting it. Cover and refrigerate, then add the cheese and finish cooking when ready to serve.
Can I use other types of cheese?
Absolutely. Cheddar, Monterey Jack, or a blend of your favorite melting cheeses work well in place of Colby Jack.

- ½ tsp sea salt (or to taste)
- ½ tsp freshly ground black pepper
- ½ tsp Worcestershire sauce
- ⅛ tsp dried thyme
Cheese
- 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 the ground beef and cook for about 5 minutes, breaking it up with a spatula, until no pink remains. Drain excess fat, leaving about 1 tablespoon of fat in the pan. Set the cooked beef aside.
- Sauté Aromatics: In the reserved fat, add the diced onion and cook for 3 to 4 minutes until the onion becomes translucent. Add the sliced mushrooms and sauté for an additional 2 minutes until they start to caramelize.
- Add Beans & Seasonings: Stir in the green beans, minced garlic, and low-sodium broth. Cook for 2 to 3 minutes until the beans turn bright green and remain crisp-tender.
- Create Creamy Base: Lower the heat to medium-low. Add the cream cheese to the skillet and stir until fully melted and smooth. Blend in the sour cream to form a creamy sauce that coats the vegetables.
- Combine & Season: Return the cooked ground beef to the skillet. Add salt, freshly ground black pepper, Worcestershire sauce, and dried thyme. Stir gently to evenly combine all the ingredients and coat them in the creamy sauce.

Notes
- Use fresh green beans if possible for best texture, but thawed frozen green beans also work well.
- For a lighter version, reduce the cheese topping to 1 cup instead of 2 cups.
- If you don’t have Worcestershire sauce, a splash of soy sauce can be a good substitute for umami flavor.
- This dish can be made in a cast-iron skillet or any oven-safe skillet suitable for broiling.
- Make sure to reserve some fat from the cooked beef to sauté the vegetables for enhanced flavor.
