Step‑by‑Step Instructions for Ultimate Green Bean Casserole with Bacon and Cheese
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it’s heating, prepare a 9×13-inch baking dish by applying a light coat of nonstick spray to ensure easy release. This will set the stage for the Ultimate Green Bean Casserole, preventing sticking and ensuring a beautifully cooked dish.
Step 2: Cook the Bacon
In a large skillet, cook about 8 slices of thick-cut bacon over medium-low heat until they turn crispy, which should take about 8-10 minutes. Once cooked, transfer the bacon to a plate lined with paper towels to drain excess grease, then crumble it into bite-sized pieces. Reserve about 2 tablespoons of the bacon grease in the skillet for added flavor.
Step 3: Sauté the Onions and Mushrooms
Using the reserved bacon grease, add 1 diced yellow onion to the skillet and sauté for approximately 5 minutes until it becomes translucent and fragrant. Next, toss in about 8 ounces of sliced button mushrooms, cooking until they turn golden brown, which should take an additional 5-7 minutes. Finish by adding 2 cloves of minced garlic and cook for another minute until aromatic.
Step 4: Combine the Casserole Ingredients
In a large mixing bowl, combine the sautéed onion and mushroom mixture with a can of undiluted cream of mushroom soup, the crumbled bacon, and ½ cup of milk. Add 1 cup of shredded Monterey Jack cheese, mixing everything together until well blended. This combination will form the creamy, flavorful base for your Ultimate Green Bean Casserole.
Step 5: Add the Green Beans
Gently fold in two cans of drained cut green beans into the mixture. Use a spatula to carefully combine the green beans with the sauce, ensuring they are evenly coated without breaking them apart. This step is vital for achieving the perfect texture in your green bean casserole.
Step 6: Transfer and Bake
Pour the mixture into the prepared baking dish, spreading it out evenly with a spatula. Top the casserole generously with about 1 cup of French fried onions, which will add a delightful crunch. Place the dish in the oven and bake uncovered for 30-35 minutes, or until the casserole is bubbly and the top is golden brown, signaling it’s ready to serve.

Make Ahead Options
These Ultimate Green Bean Casseroles are perfect for meal prep lovers! You can assemble the casserole without the French fried onions up to 24 hours in advance; just cover it tightly and refrigerate to keep the flavors fresh. This method allows the ingredients to marinate together, enhancing the taste. When you’re ready to serve, simply sprinkle the fried onions on top and bake as instructed for about 30-35 minutes until bubbly and golden. This make-ahead approach ensures a comforting dish that tastes just as delicious as when made on the spot, making your holiday gatherings smoother and stress-free!
Expert Tips for the Best Green Bean Casserole

- Refrigerate Before Baking: If preparing ahead, assemble the casserole without the fried onions, refrigerate, then add them just before baking to keep them crispy.
