How to Make the Recipe

Step 1: Cook the Beef Mixture

Heat olive oil in a large skillet over medium heat. Add ground beef and chopped onion, cooking until beef is browned and onions are translucent. Drain any excess fat.

Step 2: Add Seasoning and Tomatoes

Stir in salt, pepper, tomato paste, and minced garlic. Cook for a few minutes until fragrant. Add drained Ro-tel tomatoes and green chilies, stirring to combine. Simmer on low for 5–10 minutes.

Step 3: Cook the Noodles

Prepare wide egg noodles according to package instructions until al dente. Drain and set aside.

Step 4: Make the Creamy Cheese Sauce

In a bowl, whisk together sour cream, softened cream cheese, and cornstarch until smooth.

Step 5: Combine Ingredients

In a large mixing bowl, combine cooked noodles, beef and tomato mixture, and creamy cheese sauce. Mix until everything is evenly coated.

Step 6: Assemble the Casserole

Transfer mixture to a greased baking dish. Sprinkle shredded Colby jack cheese evenly on top.

Step 7: Bake

Bake uncovered at 350°F (175°C) for 25–30 minutes, or until cheese is melted and bubbly.

Tips for Making the Recipe

Use fresh garlic for best flavor instead of pre-minced.

Drain tomatoes well to prevent excess liquid.
Don’t overcook noodles—they’ll continue cooking in the oven.
Let the casserole rest 5 minutes before serving for easier slicing.

For extra cheesy topping, broil for 2 minutes at the end, watching carefully.

Serve Beef Lombardi Casserole warm, ideally with a crisp green salad or steamed vegetables to balance the richness. It also pairs nicely with garlic bread or a simple side of roasted veggies for a complete meal.
