Ingredients
- 1 lb ground beef (I prefer 80/20 for the best flavor)
- 1 small onion, finely chopped (Keeps things sweet and savory)
- 2 cloves garlic, minced (Adds a delightful punch!)
- 2 cups fresh or frozen green beans, cut into 1–2 inch pieces (Frozen works great in a pinch!)
- 1 can (10.5 oz) cream of mushroom soup (The creamy base for all the goodness)
- ½ cup sour cream (Adds tang and richness)
- ½ cup milk (For a smoother, creamier sauce)
- 1 teaspoon Worcestershire sauce (A secret ingredient for umami!)
- Salt and pepper, to taste (Season to your liking)
- 1½ cups shredded cheddar cheese (Sharp cheddar is my go-to)
- 2 cups frozen or refrigerated hash browns or cooked potato slices (optional, adds a lovely potato element!)
- ½ cup French fried onions or crushed Ritz crackers (For that perfect crispy topping)
How to Make It
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish. This prevents sticking and makes cleanup easier!
- In a skillet over medium heat, cook the ground beef and onion until browned. Drain off any excess fat. I like to use a paper towel-lined plate for this.
- Stir in the minced garlic and cook for about 1 minute more, until fragrant. Don’t burn the garlic!
- In a large bowl, whisk together the cream of mushroom soup, sour cream, milk, Worcestershire sauce, salt, and pepper. Make sure everything is well combined for an even flavor.
- Add the cooked beef mixture, green beans, 1 cup of the cheddar cheese, and the optional hash browns to the bowl with the sauce. Gently mix everything together.
- Pour the mixture into your prepared casserole dish. Sprinkle the remaining ½ cup of cheese evenly over the top.
- Bake uncovered for 25–30 minutes, or until the casserole is hot and bubbly. You’ll know it’s done when the cheese is melted and slightly browned.
- Sprinkle with French fried onions or crushed Ritz crackers. Bake for another 5–7 minutes, until the topping is golden brown and crispy.
- Let the casserole cool for about 5 minutes before serving. This helps it set up a bit and makes it easier to serve.
Substitutions & Additions
Feel free to experiment! You could use different cheeses, like Monterey Jack or pepper jack. Add some diced bell peppers or mushrooms to the beef mixture for extra veggies. For a spicier kick, add a pinch of red pepper flakes!
Tips for Success
- Don’t overcook the beef – it should be browned, not dry.
- Make it ahead! Assemble the casserole up to a day in advance and store it, covered, in the refrigerator. Just add the topping right before baking.
- If using fresh green beans, blanch them briefly before adding them to the casserole to ensure they are tender-crisp.
How to Store It
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.
FAQs
- Can I freeze this casserole? Yes! Assemble the casserole (without the topping) and freeze it before baking. When ready to bake, thaw overnight in the refrigerator, then add the topping and bake as directed, adding a few extra minutes to the baking time.
- What if I don’t have French fried onions? Crushed Ritz crackers make a great substitute! You can also use panko bread crumbs for a different texture.
- Can I use different beans? While green beans are traditional, you could experiment with other beans like haricots verts or even cut green beans.
