Ingredients

1 pound of thinly sliced beef (ribeye or sirloin is perfect)
1 medium onion, diced
1 green bell pepper, diced
2 cloves of fresh garlic, minced (or 1 teaspoon garlic powder for convenience)
8 ounces of mushrooms, sliced (optional but adds great flavor)
1 tablespoon olive oil (for sautéing)
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon smoked paprika (adds a lovely depth)
1 ½ cups of cooked pasta (cavatappi or rotini works great)

½ cup beef broth (for moisture)

Note: Don’t skip the fresh garlic – it adds so much punch! If you’re in a pinch, garlic powder works too.

Step-by-Step Instructions

Ready to roll up your sleeves? Here we go! This process is as simple as it is satisfying.

Preheat your oven: Preheat your oven to 350°F (175°C). A hot oven ensures that our casserole gets bubbly and golden!
Cook the veggies: In a large skillet, heat the olive oil over medium heat. Add the diced onions, bell peppers, and mushrooms. Sauté for about 5-7 minutes until they’re tender and fragrant. The aroma will be heavenly!
Add the garlic: Throw in the minced garlic, salt, pepper, and smoked paprika. Stir for about a minute until the garlic is fragrant. I always find this is the time when I wish someone else could smell my kitchen!
Cook the beef: Add the thinly sliced beef to the skillet. Cook until browned, about 3-5 minutes. Don’t overcook it – we want it juicy!
Combine the ingredients: In a large mixing bowl, combine the cooked pasta, beef mixture, and beef broth. Stir well to combine all that goodness!
Layer the casserole: Transfer half of the mixture to a greased 9×13 baking dish. Sprinkle with half of the cheese. Add the remaining mixture and top with the rest of the cheese. This layer is what dreams are made of!
Bake: Cover the dish with foil and bake for 20 minutes. Then, remove the foil and bake for another 10-15 minutes until the cheese is melted and bubbly. Let me tell you, the sight of that golden cheese is a thing of beauty!
Cool and serve: Let the casserole sit for about 5 minutes before serving. This will help everything settle a bit and makes serving so much easier.

Serving Suggestions

When it comes to serving this delicious casserole, the options are endless. I love to serve it with a simple side salad dressed in a light vinaigrette – it complements the richness of the casserole beautifully. A crusty French baguette or garlic bread also makes for a perfect pairing to soak up those cheesy, savory bites!

If you’re feeling festive, a nice cold beer or a glass of red wine adds a lovely touch to an evening meal with friends. Picture this: a cozy gathering around the dining table, laughter filling the air, and plates piled high with cheesy goodness. Sounds perfect, right?

Storage Tips

Got leftovers? Lucky you! Here’s how to keep your casserole fresh:

Refrigerate: Allow the casserole to cool completely before storing it in an airtight container. It will keep in the fridge for 3-4 days.
Freeze: You can freeze the assembled casserole prior to baking. Just cover it tightly in foil before placing it in the freezer. It will keep for up to 3 months. Just remember to thaw it in the refrigerator overnight before baking.
Reheat: To reheat, bake in a preheated oven at 350°F (175°C) for about 20-25 minutes until heated through. If it seems dry, you can add a splash of beef broth for extra moisture.

FAQs

Can I use pre-cooked beef for this casserole?

Absolutely! Using pre-cooked beef like leftover steak or rotisserie chicken will save you some time. Just make sure to heat it through with the veggies before layering it in the casserole.

Is this dish spicy?

The base recipe isn’t spicy, but you can easily crank up the heat by adding jalapeños or a pinch of red pepper flakes. It’s all about your taste preference!

Can I make this casserole ahead of time?

You can prepare the casserole ahead of time and keep it refrigerated until you’re ready to bake it. Just remember to pop it in the oven when you need it, allowing a little extra time for baking since it’s coming from the fridge.

What can I serve with the casserole?

A simple green salad, garlic bread, or even some roasted vegetables make fantastic sides. You can also serve it with a light soup for a full meal experience!

Can I use gluten-free pasta?

You bet! You can easily substitute gluten-free pasta for this recipe. Just be mindful of the cooking time, as some gluten-free pastas cook a bit differently.
