Ingredients
Here’s what you’ll need to whip up this cozy casserole. Most of these are likely staples in your pantry or fridge already!
- 1½ pounds ground beef: The hearty base of our casserole. I usually go for 80/20 for good flavor, but feel free to use leaner if you prefer – just make sure to drain the grease well!
- 1 small onion, chopped: Adds essential aromatic flavor.
- 2 cloves garlic, minced: Because everything is better with garlic, right?
- 2 (14.5 oz) cans green beans, drained (or 4 cups fresh blanched): Canned green beans are the classic shortcut here, making this super quick. Just be sure they are really well drained! If using fresh, give them a quick blanch in boiling water until tender-crisp first.
- 1 (10.5 oz) can cream of mushroom soup: The classic binder for our creamy base.
- ½ cup sour cream: Adds a lovely tang and extra richness to the sauce.
- 1½ cups shredded cheddar cheese, divided: We’ll mix some in and sprinkle some on top for maximum cheesy goodness. Sharp or mild, your call!
- 1½ cups crispy fried onions, divided: The iconic crispy topping! We’ll mix some in (trust me on this!) and pile the rest on top.
- Salt, to taste: Start with a little, you can always add more!
- Pepper, to taste: Freshly ground is always best.
How to Make It
Okay, let’s get this bubbling beauty into the oven! It’s really just a few simple steps.
1. First things first, let’s get the oven nice and hot. Preheat it to 375°F (190°C). While it’s heating up, grab your favorite 9×13 inch baking dish. You won’t need to grease it, as there’s plenty of goodness happening inside.
2. Next, take your large skillet and put it over medium-high heat. Add the ground beef and start breaking it up with a spoon or spatula. Cook it until it’s all browned through. This usually takes about 6-8 minutes. Now, this part is important for a good casserole: drain off all that excess grease. You don’t want a greasy casserole! I usually tilt the pan and scoop it out with a spoon or carefully drain it into a heat-safe container.
3. Reduce the heat slightly if your pan is still screaming hot. Add your chopped onion to the same skillet (no need to wipe it out!) and cook until it’s softened and translucent, which should take about 5 minutes. Then, stir in the minced garlic and cook for just about 1 minute more, until you can really smell that lovely garlic aroma. Don’t let it burn!
4. Now, grab a large mixing bowl. Scoop the cooked ground beef and onion mixture into the bowl. Add the well-drained green beans, the can of cream of mushroom soup, and the sour cream. Stir everything together until it’s all happy and combined. Give it a taste and season with salt and pepper. Remember the soup and cheese have salt, so start light!
5. Time for cheese and crunch! Gently fold in 1 cup of your shredded cheddar cheese and 1 cup of those crispy fried onions into the mixture. Mixing some onions into the casserole adds pockets of flavor and texture throughout, not just on top. It’s a game-changer!
6. Pour this wonderful mixture into your prepared 9×13 inch baking dish. Spread it out evenly with your spatula so you have a nice, flat surface.
7. Now for the cheesy grand finale! Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top of the casserole. Get those edges!
8. Pop the dish into your preheated oven. Bake for 20-25 minutes. You’ll know it’s ready for the next step when the edges are bubbly and the cheese on top is melted and looking gooey and delicious.
9. Take the casserole out of the oven. Now, evenly sprinkle the remaining 1/2 cup of crispy fried onions all over the top. Make sure you get good coverage for maximum crunch in every bite!
10. Return the casserole to the oven for an additional 5-7 minutes. You’re just looking for those fried onions to turn a lovely golden brown and get nice and crispy. Keep an eye on them so they don’t burn!
11. Once the onions are perfectly golden, carefully remove the casserole from the oven. It will be hot and bubbly! Let it rest for just a few minutes before you scoop it out. This helps it set up a bit and makes serving easier. Then, dig in!
Substitutions & Additions
This recipe is super forgiving and easy to customize! Here are a few ideas:
- Change the Soup: Not a fan of cream of mushroom? Cream of chicken or even cream of celery soup would work beautifully here.
- Different Meat: You could easily swap the ground beef for ground turkey or even ground sausage for a different flavor profile.
- Add Veggies: Feel free to toss in some sliced mushrooms (sauté them with the onion), diced bell peppers, or even some corn.
- Cheese Swap: Any good melting cheese would work! Gruyere, mozzarella, or a Colby Jack blend would be delicious alternatives or additions.
- Extra Flavor: A pinch of garlic powder or onion powder stirred into the mixture can boost the flavor even more. A little dash of Worcestershire sauce with the meat is also great.
- Crispy Topping Swap: If you don’t have fried onions, you could top it with breadcrumbs mixed with a little melted butter, crushed crackers, or even crushed potato chips!
Tips for Success
Just a couple of little pointers to make sure your casserole turns out perfectly every time:
- Drain the Grease! I know I mentioned it, but seriously, this is key. Too much grease makes the casserole oily.
- Don’t Skimp on the Onions: Adding some fried onions into the casserole mixture really makes a difference in flavor and texture throughout the dish.
- Watch the Final Bake: The second bake for the crispy onions is quick! Keep an eye on them so they turn golden, not black.
- Prep Ahead: You can cook the meat and onion mixture and mix it with the green beans, soup, sour cream, and inner cheese/onions. Store it in the baking dish, covered, in the fridge for up to 24 hours. When ready to bake, add the topping cheese and bake as directed, adding a few extra minutes to the initial bake time if needed since it’s cold. Add the final crispy onions for the last 5-7 minutes.
How to Store It
Leftovers of this casserole, if there are any (ha!), store really well.
Let the casserole cool completely. Cover the baking dish tightly with plastic wrap or aluminum foil, or transfer individual portions to airtight containers. It will keep in the refrigerator for 3-4 days. To reheat, you can microwave individual servings or place the covered dish in a 350°F (175°C) oven until heated through. The crispy onions might soften a bit upon reheating, but it will still be delicious!
FAQs
Got questions? I’ve got answers!
Can I use frozen green beans?
Yes, you absolutely can! Just make sure they are thawed and really well drained before adding them to the mixture. Patting them dry with paper towels helps prevent a watery casserole.
Can I make this ahead of time?
Definitely! As mentioned in the tips section, you can assemble the base mixture (everything except the final cheese and crispy onions) and refrigerate it for up to a day. Add the cheese and bake when you’re ready, then add the crispy onions for the last few minutes.
What do I serve with this?
This casserole is pretty hearty on its own, but it pairs wonderfully with simple sides like mashed potatoes, a simple green salad, or some crusty bread to soak up the deliciousness!
