Step‑by‑Step Instructions for Hamburger Green Bean Casserole with Mushrooms Step 1: Brown the Beef In a large skillet, heat over medium heat, adding the ground beef to the hot pan. Cook for about 5 minutes, stirring until the meat is browned and no longer pink. Once done, remove the beef from the skillet but be sure to reserve 1 tablespoon of the rendered fat in the pan for added flavor. Step 2: Sauté Aromatics In the same skillet with the reserved beef fat, add the diced onion. Sauté for 3-4 minutes until the onion turns translucent and fragrant. Next, toss in the sliced mushrooms and continue to cook for an additional 2 minutes, allowing the mushrooms to soften and release their moisture, enhancing the flavors for our Hamburger Green Bean Casserole with Mushrooms. Step 3: Add Beans and Seasonings Stir in the trimmed green beans, minced garlic, and your choice of beef or chicken broth. Cook for 2-3 minutes, stirring occasionally, until the green beans are bright and just tender. This quick step keeps them crisp while melding them beautifully with the sautéed onion and mushrooms for a hearty, satisfying base. Step 4: Create Creamy Base Reduce the heat to medium-low. Add the cream cheese to the skillet, stirring until it’s fully melted and combined. Once smooth, add the full-fat sour cream and mix until the creamy sauce is luscious and velvety. This rich base will envelop all the vegetables and beef in your Hamburger Green Bean Casserole with Mushrooms. Step 5: Combine and Season Return the browned beef to the skillet, incorporating it into the creamy mixture. Sprinkle in sea salt, black pepper, Worcestershire sauce, and dried thyme. Stir well to evenly distribute all seasonings, ensuring each bite of the casserole is packed with flavor and comforting goodness. Step 6: Add Cheese Topping Once everything is well combined, sprinkle the shredded Colby Jack cheese evenly over the top of the casserole. This cheesy layer will create a deliciously gooey topping that complements the savory blend of beef and vegetables below. Step 7: Melt Cheese To melt the cheese perfectly, either broil the casserole on high for 1-2 minutes until bubbly and golden, keeping a close eye to avoid burning, or cover the skillet and cook on low heat until the cheese melts beautifully. This last touch brings your Hamburger Green Bean Casserole with Mushrooms together in a deliciously satisfying way.
