Step‑by‑Step Instructions for Hamburger Green Bean Casserole with Mushrooms
Step 1: Brown the Ground Beef
In a large skillet over medium heat, brown 1 pound of ground beef until it’s fully cooked and no longer pink, about 5 minutes. Use a wooden spoon to break apart any large chunks, making sure to let it develop a nice browning. Once done, carefully drain excess grease, but reserve about 1 tablespoon in the skillet for flavor.
Step 2: Sauté Aromatics
In the same skillet with reserved beef fat, add one diced onion. Sauté over medium heat until the onion is translucent and fragrant, about 3-4 minutes. Then, stir in 8 ounces of sliced mushrooms, allowing them to caramelize for an additional 2 minutes, which will add depth to your Hamburger Green Bean Casserole with Mushrooms.
Step 3: Add Green Beans and Seasonings
Mix in 1 pound of fresh or thawed frozen green beans along with 2 minced garlic cloves and 1 cup of beef or chicken broth. Cook everything together for 2-3 minutes, stirring occasionally until the green beans are bright, crisp-tender, and all the flavors meld beautifully.
Step 4: Create Creamy Base
Lower your heat to medium-low and introduce 4 ounces of softened cream cheese to the skillet, stirring constantly until it blends smoothly into the mixture. Next, add ½ cup of sour cream, mixing well until everything is creamy and combined, forming the luscious base for your casserole.
Step 5: Combine and Season
Return the browned ground beef to the pan, and season the mixture with sea salt, black pepper, 1 tablespoon Worcestershire sauce, and 1 teaspoon dried thyme. Stir everything together thoroughly, ensuring that the spices and beef are evenly distributed throughout the creamy casserole base.
Step 6: Add Cheese Topping
Sprinkle 1 ½ cups of shredded Colby Jack cheese evenly over the top of the casserole. This will melt and create a delightful, gooey texture as the casserole cooks, adding a delicious finish to the Hamburger Green Bean Casserole with Mushrooms.
Step 7: Melt Cheese
For the final step, you can either broil the casserole for 1-2 minutes or cover it and let it cook on low heat for an additional 3-4 minutes, ensuring the cheese is melted and bubbly. Keep a close eye on it to achieve your desired level of cheesy goodness!
