Step-by-Step Instructions
This Beef Lombardi Casserole is easy to put together in just 5 simple steps:
- Cook the meat – In a large skillet over medium-high heat, cook the ground beef until fully browned. Drain any excess fat.
- Make the sauce – Stir in the diced tomatoes, diced tomatoes with green chiles, tomato paste, and seasonings. Simmer for 15-20 minutes to develop the flavors.
- Prepare the noodles – Cook the egg noodles according to package instructions until al dente. Drain and toss with the sour cream until evenly coated.
- Assemble the casserole – In a greased 9×13 baking dish, layer the creamy noodles, top with the beef mixture, and sprinkle with the shredded cheese blend.
- Bake – Cook at 350°F for 20-25 minutes until hot, bubbly, and perfectly melted. Let it rest for a few minutes before serving.
That’s it! Just bake until golden and irresistible.
Pro Tips for the Best Casserole
- Don’t overcook the noodles – Keep them slightly firm since they’ll soften while baking.
- Boost the sauce’s richness – Simmer the beef mixture a little longer for deeper, concentrated flavors.
- Enhance the creaminess – Add a splash of pasta cooking water to the sour cream before tossing with the noodles.
- Keep the cheese perfect – Tent foil over the dish if the cheese browns too quickly before the casserole is fully heated through.
