The Longhorn Steakhouse Casserole is a delightful homage to the beloved steakhouse experience, bringing the flavors of a savory steak dinner into a hearty baked dish. This casserole combines ground beef with rich, creamy ingredients and a blend of cheeses that create a comforting meal perfect for any occasion.
Ingredients
Scale:
1 pound ground beef, preferably a mix of lean and fatty for optimal flavor
1 cup diced onions, about one medium onion
2 cloves garlic, minced, or more if you love garlic
1 can (15 oz) diced tomatoes, undrained, ideally with green chilies for added flavor
1 can (15 oz) black beans, rinsed and drained, or you can use pinto beans for a different taste
1 cup corn kernels (fresh or frozen), sweet corn works best
1 teaspoon chili powder, adjust to taste for spiciness
1 teaspoon cumin, which adds a nice earthiness
Salt and pepper to taste, remember to season in layers
2 cups cooked rice (white or brown), using leftover rice can save time
1 cup sour cream, full-fat gives the best consistency
1 cup cream of mushroom soup, store-bought or homemade
1 cup shredded cheddar cheese, sharp cheddar provides a more robust flavor
1 cup shredded Monterey Jack cheese, or a blend for extra creaminess
1 cup crushed tortilla chips (optional), adds a delightful crunch
1/2 cup additional shredded cheese (for topping), consider a mix of cheeses for depth
Fresh cilantro for garnish (optional), adds a pop of color and freshness
Instructions
Preheat your oven to 350°F (175°C) to ensure even baking.
In a large skillet over medium heat, brown the ground beef until fully cooked, about 5-7 minutes. Drain any excess fat to keep the casserole from becoming greasy.
Add the diced onions and minced garlic to the skillet. Sauté until the onions are translucent, about 3-4 minutes, stirring occasionally to prevent sticking and ensure even cooking.
Stir in the diced tomatoes, black beans, corn, chili powder, cumin, salt, and pepper. Cook for an additional 5 minutes, allowing the flavors to meld together and intensify.
In a large bowl, combine the cooked rice with the creamy sauce ingredients: sour cream, cream of mushroom soup, and the shredded cheeses. Mix well until creamy and smooth, ensuring that the cheeses are evenly distributed.
Fold the beef and vegetable mixture into the creamy rice mixture until fully combined, making sure every bite has a balanced flavor profile.
Transfer the mixture into a greased 9x13 inch baking dish, spreading it evenly to ensure uniform baking.
If using, sprinkle the crushed tortilla chips on top, followed by the remaining shredded cheese for a delectable crispy topping.
Bake in the preheated oven for 25-30 minutes or until the top is bubbly and golden brown, with the edges slightly crispy.
Remove from the oven and let the casserole cool slightly before serving. Garnish with fresh cilantro if desired, as it adds a refreshing contrast to the rich flavors.
