How To Make Ground Beef Casserole with Green Beans
Bringing all these ingredients together is a breeze, and the result is pure comfort in a casserole dish. You’ll sauté, simmer, and bake your way to layers of flavor while the kitchen fills with mouthwatering scents. Follow these detailed steps to ensure each component—meat, beans, tomatoes, and cheese—blends harmoniously into a golden, bubbling masterpiece.
1. Preheat your oven to 375°F (190°C), ensuring it reaches the right temperature before baking for an even cook.
2. In a large skillet over medium heat, heat olive oil until shimmering, which prevents sticking and helps develop flavor.
3. Add the diced onion and cook, stirring occasionally, until translucent—about 5 minutes—so you get those sweet, soft onions.
4. Stir in the minced garlic and cook for 1 more minute until fragrant and slightly golden, being careful not to burn it.
5. Add the ground beef to the skillet, breaking it up with a spoon or spatula, and cook until fully browned, about 5–7 minutes.
6. Stir in the diced tomatoes, drained green beans, dried oregano, and dried basil, mixing thoroughly to coat the beef.
7. Season with salt and pepper, then reduce the heat and let the mixture simmer for 5 minutes to meld the flavors.
8. Transfer the beef and bean mixture to a greased 9×13-inch baking dish, spreading it into an even layer.
9. Sprinkle the shredded cheddar cheese evenly over the top, then add the breadcrumbs for a crunchy, golden finish.
10. Bake in the preheated oven for 20–25 minutes, until the cheese is melted and the breadcrumbs turn golden brown.
11. Remove from the oven and let the casserole rest for 5 minutes before serving to help it set and make slicing easier.
