- 1 cup shredded cheddar cheese (sharp cheddar adds great flavor)

- ½ cup cream cheese, softened

Step-by-Step Instructions
Let’s break this recipe down step by step so it’s foolproof every time:
Step 1: Preheat the Oven
Set your oven to 375°F (190°C) so it’s ready once your casserole mixture is prepped.
Step 2: Cook the Aromatics
In a large skillet, heat olive oil over medium heat. Add the diced onion and sauté for 2–3 minutes until soft and fragrant.
Step 3: Brown the Beef
Add the ground beef to the skillet. Cook for 6–8 minutes, breaking it up with a spatula, until fully browned. Drain any excess fat if necessary.
Step 4: Add Seasonings
Stir in minced garlic, salt, pepper, paprika, onion powder, and garlic powder. Mix well to coat the meat with the spices.
Step 5: Create the Creamy Sauce
Reduce heat to low. Add the cream cheese and sour cream. Stir until the cream cheese melts and everything is combined into a smooth, creamy sauce.
Step 6: Add Green Beans
Meanwhile, steam or boil your green beans for 3–4 minutes, just until tender-crisp. Drain and add them to the beef mixture. Stir until evenly combined.
Step 7: Assemble the Casserole
Transfer the entire mixture into a lightly greased baking dish. Sprinkle shredded cheese evenly over the top. If you’re adding a crunchy topping, now’s the time.
Step 8: Bake
Place in the oven and bake uncovered for 20–25 minutes, or until the cheese is golden and bubbling.
Step 9: Serve and Enjoy
Let it rest for 5 minutes before serving to allow the layers to set.

Crushed pork rinds, almond flour, or even shredded Parmesan make a crispy, golden topping.
