Put raw sliced onions in casserole. A few ingredients later: A rich, savory masterpiece!

This beef and onion bake is one of those recipes that feels like a warm hug after a long day. Growing up in the Midwest, casseroles were a staple at every family gathering, and this dish is a nod to that tradition. With just six ingredients, it's perfect for busy weeknights when you want something hearty and satisfying without spending hours in the kitchen. It's also a great way to use up any ground beef you might have in the fridge, and the simplicity of the ingredients lets the flavors really shine.

This beef and onion bake pairs wonderfully with a simple green salad or some steamed vegetables to balance out the richness of the dish. If you're feeling a bit indulgent, a side of buttery mashed potatoes or some crusty bread would complement it perfectly. For a lighter option, try serving it with a side of roasted Brussels sprouts or a fresh cucumber salad.

Servings: 4

1 pound ground beef
2 large onions, thinly sliced
1 cup shredded cheddar cheese
1 can (10.5 oz) cream of mushroom soup
1/2 cup milk
1 teaspoon salt

Preheat your oven to 350°F (175°C).

In a large skillet over medium heat, cook the ground beef until browned and cooked through. Drain any excess fat.

Add the sliced onions to the skillet with the beef and cook until the onions are soft and translucent.

In a mixing bowl, combine the cream of mushroom soup, milk, and salt. Stir until smooth.

Layer the beef and onion mixture in a baking dish, then pour the soup mixture over the top.

Sprinkle the shredded cheddar cheese evenly over the dish.

Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden.

Let it cool for a few minutes before serving.

For a bit of spice, add a teaspoon of chili powder or a dash of hot sauce to the beef while cooking. If you prefer a different cheese, try swapping the cheddar for Monterey Jack or pepper jack for a little kick. You can also add some sliced mushrooms or bell peppers to the onion mixture for extra veggies. For a gluten-free version, make sure to use a gluten-free cream of mushroom soup.
