❤️ Why You Will Love This Recipe

Let’s get into why this easy keto ground beef casserole recipe is going to be your new go-to. First off, it’s:

  • Super satisfying: It’s hearty and filling, perfect for those nights when you want something that feels indulgent but still keeps you on track.
  • Easy recipe: With straightforward steps and simple ingredients, this casserole comes together with minimal fuss.
  • Versatile: It’s easy to tweak based on what you have on hand. No ricotta? Mascarpone or cream cheese will do the trick.
  • Family-friendly: Even if not everyone’s following a keto diet, this dish is a crowd-pleaser.
  • Perfect for meal prep: Make it once, and you’ve got a delicious meal ready to go for the next few days.
  • Low in carbs: Focused on keeping it keto, this casserole keeps the carb count low (5g net carbs per serving) without sacrificing flavor.

🗝️ Key Ingredients & Substitutions

This casserole is packed with flavor, thanks to a combo of carefully chosen ingredients. Here’s the lowdown on what you’ll need and how you can switch things up if necessary:

  • Ground beef: The star of the show. Go for lean or with a bit more fat, depending on your preference. Feel free to sub in ground turkey or chicken for a lighter option.
  • Worcestershire sauce & Tomato paste: These add a deep, rich flavor to the beef. If you’re out of Worcestershire, soy sauce or a dash of balsamic vinegar can pinch-hit.
  • Mustard, garlic powder, onion powder: For that punch of flavor. Easy to adjust based on what’s in your spice rack.
  • Beef broth: Gives the casserole a saucy texture. Vegetable broth works too.
  • Green beans: Fresh green beans or frozen, they add a nice crunch. Swap in broccoli or asparagus if you’re looking to mix it up. Canned green beans will work too, they just won’t have the same bite.
  • Salt & Ground black pepper: Basics for seasoning. Adjust to taste.
  • Ricotta: For creaminess. Substitute cream cheese or mascarpone as needed. Each brings a slightly different texture and flavor, so use what you like or have on hand.
  • Eggs: Help to bind everything together. No real substitute here, so make sure you’ve got them!
  • Cheddar cheese: For that cheesy top layer. Swap in mozzarella cheese (for that cheese pull!), Monterey Jack, or even a mix of your favorite melty cheeses.

🥣 How to Make Keto Green Bean Hamburger Casserole

Whipping up this low-carb casserole is as easy as pie (or, well, easier, because pie can actually be kinda tricky). Let’s break it down:

1. Brown the Beef

Start by heating up a large skillet over medium heat. Toss in the lean ground beef and cook it until it’s nicely browned and crumbly. This is where all the flavor starts, so don’t rush it!

2. Add the Flavors

Once your hamburger meat is cooked, stir in the Worcestershire sauce, tomato paste, mustard, garlic powder, onion powder, and beef broth. This combo is going to make your kitchen smell amazing and give the casserole its rich, savory base.

3. Mix in the Green Beans

Turn off the heat and mix those green beans right into the skillet with the ground beef mixture. They’ll get a bit of flavor love from all that beefy goodness.

4. The Creamy Mix

In a separate bowl, whisk your eggs. Then, add in the ricotta (or cream cheese/mascarpone) and give it a good mix until smooth. This is the creamy, dreamy part of the casserole.

5. Combine and Bake

Pour that creamy egg mixture into your skillet with the beef and beans, giving everything a good stir to make sure it’s well combined. Then, transfer the whole shebang into a 9×13″ casserole dish. Sprinkle the cheddar cheese on top of the casserole, and then bake it in the oven at 355°F/180°C for about 25 minutes. You’re looking for a golden, bubbly top.

6. Rest and Serve

Give it a 10-minute rest after taking it out of the oven; this helps everything set up nicely. Then, dive in and enjoy the fruits of your labor!

🪄 Recipe Notes & Tips

Making this keto hamburger casserole is a breeze, but here are a few nuggets of wisdom to make sure it turns out awesome every time:

  • Don’t skip the resting time: It might be tempting to cut into it right away, but giving it a few minutes helps everything set and makes serving easier.
  • Customize the spice level: If you like things with a bit more kick, don’t hesitate to add some red pepper flakes, diced jalapeños, or hot sauce into this keto casserole recipe.
  • Check for seasoning: After adding the beef broth and before combining everything, give it a taste and adjust the salt and pepper if needed.
  • Low-carb topping options: If you’re missing the fried onions on top of traditional casseroles, try a sprinkle of almond flour mixed with grated parmesan cheese and a little bit of olive oil for the last 5 minutes of baking for a crispy finish.
  • Make it ahead: You can assemble this casserole a day ahead and keep it in the fridge. Just add a few minutes to the baking time since you’ll be starting from cold.

🫙 Storage Instructions

Leftover casserole? If you’re lucky enough to have any, here’s how to keep them tasting great:

  • Cool & Airtight: Make sure the casserole is at room temperature and store it in an airtight container.
  • Fridge or freeze: In the fridge, your casserole will stay good for 3-4 days. If you’re thinking longer term, you can freeze it for up to 2 months. Just make sure it’s wrapped well or in a freezer-safe container.
  • Reheating: When you’re ready to enjoy it again, you can reheat slices in the microwave, or for a crispier top, pop it back into the oven at 350°F until it’s heated through.
  • Freeze before baking: You can assemble the casserole, cover it tightly, and freeze before baking. When you’re ready to cook it, let it thaw in the fridge overnight, then bake as directed, adding a few extra minutes if needed.

🍽️ What To Serve With Keto Green Bean Hamburger Casserole

Now, you’ve got this gorgeous casserole ready to go, but what about the sides? Here’s how to make this a complete meal:

Keep It Low-Carb

  • Cauliflower Rice: A no-brainer for keto fans. It’s light, fluffy, and soaks up any of that casserole gravy beautifully. Plus, it’s super easy to flavor however you like.
  • Salad: A crisp, fresh salad with a zippy vinaigrette balances the richness of the casserole perfectly. Think greens, cucumbers, radishes, and a sprinkle of feta for a bit of tang.

Add Some Crunch

  • Air Fried or Roasted Veggies: Broccoli, Air Fryer Brussels Sprouts, or asparagus roasted with a little olive oil, salt, and pepper make a simple, healthy side that adds a nice bit of texture.
  • Keto Bread or Biscuits: If you’re in the mood for something bread-y, there are tons of keto recipes out there for biscuits or rolls that use almond flour or coconut flour.

Comfort on the Side

  • Creamed Spinach: Another low-carb favorite that’s creamy and comforting, just like the casserole.
  • Mashed Cauliflower: If you’re missing mashed potatoes, mashed cauliflower is a fantastic substitute. Add some roasted garlic and a bit of cheese, and you’ve got a side dish that everyone will love.

❓ Frequently Asked Questions

Is this keto casserole recipe spicy?

Not as it’s written, but it’s super easy to spice up. Add some chili flakes, cayenne pepper, or even a bit of jalapeño to the beef mixture for a kick.

Can I use canned green beans instead of fresh?

Absolutely. If you’re in a pinch or that’s what you have on hand, canned green beans will work just fine. Just drain them well before adding them to the mix.

How can I make this casserole creamier?

If you’re after an even creamier texture, consider adding more ricotta or cream cheese. You could also stir in a splash of heavy cream to the beef mixture before baking.
