Ingredients You’ll Need
Crafting the perfect Hamburger Green Bean Casserole starts with understanding the role of each component. Here’s a breakdown of the core ingredients and how to choose them, along with substitution advice to cater to every taste and dietary need.
The Foundation: Ground Beef
The star of our show! For this ground beef green bean casserole, we recommend using 80/20 lean ground beef. The slightly higher fat content adds flavor and richness, though you’ll want to drain off any excess grease after browning to prevent a greasy casserole. If you prefer a leaner option, 90/10 or even ground turkey or chicken work beautifully; just be sure to add a little extra olive oil to the pan if browning leaner meats to prevent sticking. You could even swap in ground sausage for a different flavor profile.
The Veggies: Green Beans
For convenience and classic flavor, canned green beans are the go-to for many. They are already cooked and tender, needing just a good drain before mixing. Frozen green beans are also an excellent choice; simply thaw and drain them well to avoid a watery casserole. If you prefer fresh green beans, blanch them briefly in boiling salted water for 3-5 minutes until crisp-tender, then drain thoroughly before adding to the mixture.
The Creamy Binder: Cream of Mushroom Soup
This is the secret to that classic, luscious texture. Campbell’s cream of mushroom soup is often considered the traditional choice for green bean casseroles, providing a savory depth. Feel free to experiment with other condensed ‘cream of’ soups like cream of chicken or cream of celery for subtle flavor variations. If you’re avoiding canned goods, a simple homemade cream sauce can be whipped up with butter, flour, milk, and sautéed mushrooms for a fresh alternative.
The Essential Topping: Crispy Fried Onions
No creamy green bean casserole recipe is complete without them! These crispy fried onions add a delightful crunch and savory onion flavor that perfectly complements the creamy filling. If you’re looking for alternatives, consider crushed Ritz crackers mixed with melted butter, panko breadcrumbs for a lighter crisp, or a generous layer of shredded cheese. For a truly unique twist, especially for a green bean casserole with tater tots and ground beef, you can layer frozen tater tots on top for the final bake!
Flavor Boosters & Optional Add-Ins
Elevate your Hamburger Green Bean Casserole with simple additions. Sautéing diced onions and minced garlic with the ground beef provides an aromatic base. A splash of Worcestershire sauce or a dash of soy sauce can deepen the umami flavor. Don’t forget staple seasonings like black pepper, garlic powder, and onion powder to taste.
Step-by-Step Instructions: How to Make Hamburger Green Bean Casserole
Ready to whip up this incredible weeknight dinner recipe? Follow these simple steps for a perfect ground beef and green bean casserole every time.
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with cooking spray or butter. This ensures easy cleanup and prevents sticking.
Step 2: Brown the Ground Beef
In a large skillet, cook 1 pound of ground beef over medium-high heat, breaking it apart with a spoon as it browns. If desired, add 1/2 cup diced onion and 2 cloves minced garlic during the last few minutes of cooking for extra flavor. Once the beef is fully cooked and no longer pink, drain off any excess grease thoroughly. This step is crucial for preventing a soggy casserole.
Step 3: Mix the Casserole Base
In the same skillet (or a large mixing bowl), combine the cooked and drained ground beef with two (14.5 ounce) cans of well-drained green beans, one (10.5 ounce) can of condensed cream of mushroom soup, 1/2 teaspoon black pepper, and 1/2 teaspoon garlic powder. Stir gently until all ingredients are well combined and the green beans are evenly coated in the creamy sauce.
Step 4: Assemble and Bake
Transfer the hearty beef and green bean mixture to your prepared casserole dish. Spread it into an even layer using the back of a spoon. Bake in the preheated oven for 20-25 minutes, or until the casserole is heated through and the edges are gently bubbling.
Step 5: Add the Topping and Final Bake
Remove the casserole from the oven. Sprinkle 1 to 1 1/2 cups of crispy fried onions evenly over the top. If you’re making a cheesy hamburger green bean bake, this is also the perfect time to add a layer of shredded cheese. Return the casserole to the oven and bake for an additional 5-10 minutes, or until the fried onions are golden brown and crispy, and any added cheese is melted and bubbly. Serve hot and enjoy your delicious Hamburger Green Bean Casserole!
Pro Tips for Casserole Perfection
Even a simple recipe benefits from a few expert touches. Follow these tips for the best ground beef casserole:
- Season Every Layer: Don’t just rely on the soup for flavor. Season your ground beef as it browns with salt and pepper, and taste the casserole mixture before baking to adjust seasonings.
- Don’t Overmix: Gently fold the ingredients together. Overmixing can break down the green beans and create a less appealing texture.
- Prevent a Soggy Casserole: The most common culprit for a watery casserole is excess moisture. Ensure your green beans are well-drained, and always take the time to drain all excess grease from the ground beef.
- Let It Rest: Just like a good roast, allowing the casserole to sit for 5-10 minutes after baking helps it set up. This makes for cleaner slices and easier serving.
- Choosing the Right Dish: A ceramic or glass baking dish works best as it heats evenly and retains heat well, keeping your casserole warm longer.
Delicious Variations & Customizations
This Hamburger Green Bean Casserole is a fantastic canvas for your culinary creativity. Here are some popular ways to customize it, ensuring you’ll never get bored of this versatile dish!

Cheesy Hamburger Green Bean Casserole
For the ultimate cheesy hamburger green bean bake, simply stir 1 cup of shredded cheddar cheese (or Colby Jack, mozzarella, or a blend) into the casserole mixture before baking. For an extra cheesy top, sprinkle another 1/2 to 1 cup of cheese over the fried onions during the last 5-10 minutes of baking.
Loaded Tater Tot Casserole Style
Want to combine the best of both worlds? For a satisfying twist reminiscent of a classic tater tot casserole, prepare the hamburger green bean mixture as directed. Instead of crispy fried onions, arrange a single layer of frozen tater tots over the top of the casserole. Bake for 30-35 minutes, or until the tots are golden brown and crispy, adding a fantastic texture and heartiness.
Make it Low-Carb / Keto-Friendly
It’s easy to adapt this recipe for a keto hamburger green bean casserole. First, use fresh or frozen green beans (ensure no-sugar-added) instead of canned. Instead of canned soup, create a homemade cream sauce using heavy cream, broth, a touch of cream cheese, and a pinch of xanthan gum for thickening. Skip the fried onions and top with a mixture of shredded cheese and crushed pork rinds for that satisfying crunch.
Add More Veggies
Boost the nutritional value and flavor by adding extra vegetables. Sauté sliced mushrooms, diced carrots, or corn kernels along with the ground beef. Frozen mixed vegetables can also be thawed, drained, and stirred in with the green beans.
Spice It Up
If you like a little heat, incorporate a pinch of red pepper flakes into the ground beef mixture, or add a dash of your favorite hot sauce. Using spicy ground sausage instead of beef also offers a flavorful kick.
What to Serve with Your Casserole
Since this Hamburger Green Bean Casserole is a complete and hearty main dish on its own, simple sides are best to complement its rich flavors.
- Starchy Sides: Fluffy dinner rolls or crusty bread for soaking up the creamy sauce. Mashed potatoes or white rice are also classic pairings.
- Light & Fresh Salads: A crisp green salad with a bright vinaigrette dressing helps to cut through the richness of the casserole, offering a refreshing contrast.
- Roasted Vegetables: A side of roasted broccoli, asparagus, or glazed carrots can add extra nutrients and texture without overpowering the main dish.
Storage, Freezing, and Reheating Instructions
This make-ahead casserole is perfect for meal prep or enjoying delicious leftovers. Here’s how to store it properly.
How to Store Leftovers
Allow any leftover Hamburger Green Bean Casserole to cool completely before transferring it to an airtight container. Store it in the refrigerator for up to 3-4 days.
Can You Freeze Hamburger Green Bean Casserole?
Yes, this casserole freezes beautifully! For best results, it’s generally recommended to freeze it without the crispy fried onion topping, as they can get soggy upon thawing.
- To Freeze Unbaked: Assemble the casserole as directed (without the fried onions). Cover tightly with plastic wrap, then aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before baking, adding about 10-15 minutes to the initial bake time. Add fried onions for the last 5-10 minutes as usual.
- To Freeze Baked: Allow the casserole to cool completely. Divide into individual portions or freeze the entire casserole (again, without the fried onions if possible, adding them fresh upon reheating). Cover tightly and freeze for up to 2-3 months.
The Best Way to Reheat
- Oven: For the crispiest results, especially if adding fresh fried onions, reheat portions or the entire casserole in an oven preheated to 350°F (175°C) until heated through and bubbly. Cover with foil to prevent drying, then remove for the last few minutes if desired.
- Microwave: For individual portions, the microwave is the fastest method. Reheat on medium power, stirring occasionally, until hot. The topping won’t be as crispy, but it will still be delicious.
Frequently Asked Questions (FAQ)
Can I make this casserole ahead of time?
Absolutely! You can assemble the entire Hamburger Green Bean Casserole (without the crispy fried onion topping) 1-2 days in advance. Cover it tightly and store it in the refrigerator. When ready to bake, add about 10-15 minutes to the initial baking time to account for starting with a cold casserole. Add the topping for the final 5-10 minutes as usual.
What can I use instead of cream of mushroom soup?
If cream of mushroom soup isn’t your preference, you have several options. You can use other ‘cream of’ soups like cream of chicken or cream of celery soup. Cheddar cheese soup also works well for a cheesy variation. Alternatively, you can make a simple homemade white sauce (roux-based with milk or broth) and add seasonings.
Can I use ground turkey or chicken instead of beef?
Yes, you can! Ground turkey or ground chicken are excellent leaner alternatives to ground beef. Just be sure to season them well as they can be milder in flavor. You might also need to add a touch more olive oil when browning if using very lean poultry to prevent sticking.
How do I know when the casserole is fully cooked?
Your Hamburger Green Bean Casserole is fully cooked when the edges are visibly bubbling, and the center is thoroughly heated through. If you want to be precise, an instant-read thermometer inserted into the center should register 165°F (74°C).
My casserole is watery. What went wrong?
A watery casserole usually stems from excess moisture. The most common reasons are not properly draining the canned or thawed green beans, or not draining enough grease from the cooked ground beef. Ensure both components are as dry as possible before mixing them into the casserole base. If using frozen green beans, thaw them completely and squeeze out any excess water.
Conclusion
This Hamburger Green Bean Casserole truly is the ultimate expression of comfort food, blending ease, flavor, and budget-friendliness into one irresistible dish. It’s a testament to how simple ingredients can create something extraordinary, perfect for any weeknight or special gathering.
