Onion (Diced – Yellow or White) – Amust-have for savory depth; opt for shallots if you prefer a milder flavor.
Mushrooms (Sliced Button or Baby Bella) – Adds earthiness to the dish; feel free to use cremini or portobello mushrooms as substitutes.
Minced Garlic – Boosts the flavor profile; fresh is ideal, but garlic powder (1 tsp) can work in a pinch.
Beef or Chicken Broth (Low-Sodium) – This adds moisture; swap for vegetable broth for a vegetarian-friendly option.

For the Creamy Sauce

Sour Cream – Contributes to the creaminess; Greek yogurt makes a tangy alternative if desired.
Cream Cheese – This gives the sauce its rich, silky texture; alternative soft cheeses like mascarpone can also be used.
Sea Salt and Black Pepper – Essential for seasoning; adjust to taste based on your preference.

Step‑by‑Step Instructions for Hamburger Green Bean Casserole with Mushrooms

Step 1: Brown the Beef
Heat a large cast-iron skillet over medium heat. Add the ground beef and cook for about 5 minutes, breaking it apart with a spatula as it browns. Look for a rich, golden color before draining the excess fat, but be sure to reserve 1 tablespoon to enhance flavors. Transfer the cooked beef to a plate and set aside.

Step 2: Sauté Aromatics
In the same skillet, add the reserved beef fat, then toss in the diced onion. Sauté for 3-4 minutes, stirring occasionally, until the onion becomes translucent and fragrant. Next, add the sliced mushrooms and cook for an additional 2 minutes, allowing them to caramelize slightly and develop a deeper flavor in this Hamburger Green Bean Casserole.

Step 3: Add Beans & Seasonings
Stir in the green beans, minced garlic, and your choice of low-sodium beef or chicken broth. Cook this mixture for 2-3 minutes until the green beans turn bright green and become crisp-tender. The aromas will fill your kitchen, signaling that it’s time to move to the next step in crafting this hearty casserole.

Step 4: Create Creamy Base
Reduce the heat to medium-low, then introduce the cream cheese into the skillet. Stir until the cream cheese melts and creates a smooth consistency, followed by mixing in the sour cream. This will form a rich and creamy sauce that beautifully envelops the savory components of the Hamburger Green Bean Casserole.

Step 5: Combine & Season
Add the cooked ground beef back into the skillet, followed by a sprinkle of sea salt, black pepper, Worcestershire sauce, and dried thyme. Stir gently to combine everything, ensuring the beef and vegetables are evenly coated in the creamy sauce. Look for a harmonious blend of flavors as you thoroughly mix the ingredients together.

Step 6: Cheese Topping
Evenly sprinkle the shredded Colby Jack cheese over the mixture in the skillet, covering every inch for that delicious melty goodness. Be generous, as it will create a beautiful cheese layer on top of your Hamburger Green Bean Casserole, enhancing both flavor and presentation.

Step 7: Melt & Serve
To finish, you have two options: Option A, broil the skillet on high for 1-2 minutes until the cheese is bubbling and golden. Option B, simply cover and cook on low for 3-4 minutes until the cheese is melted and gooey. Serve hot and enjoy the comforting flavors of this Hamburger Green Bean Casserole with Mushrooms!
