🔪 Making Zucchini Hamburger Casserole

Would you look at how easy this dish is to create?! You are just 4 simple steps away from creating a delicious beef and vegetable casserole that your whole family will love!

Brown the Ground Beef

In a cast-iron skillet, cook the ground beef on medium heat until browned, about 5 minutes.

Remove ground beef and drain grease, leaving 1 Tbsp of the grease in the pan to saute the vegetables in.

Saute the Veggies

In the same skillet, cook the chopped onions over medium heat until they start to soften, about 3 minutes. Add the garlic to the pan and cook for 1 more minute.

Add the zucchini and broth to the pan and cook until the zucchini is soft, about 5 more minutes.

Add Cheeses

Turn the heat down to medium-low add the cream cheese and then sour cream.

Add the beef back into the pan along with the salt, pepper, and Worcestershire sauce. Stir gently to combine.

Sprinkle with the cheddar cheese over the top.

Broil

Place the entire dish in the oven and broil for 2 minutes until the cheese is browned and melted. Or, add lid to skillet and cook for 3-4 minutes until the cheese melts. Using the stovetop, your cheddar cheese won’t be crispy, but it will melt.

💡Recipe Tips

You can easily substitute ground turkey or chicken instead of ground beef.
If you don’t think cheddar is better, feel free to use your favorite shredded cheese.
If you don’t have a cast-iron skillet or other oven-safe pan, be sure to transfer the casserole to an oven-safe dish before broiling.
This recipe does call for a lot of zucchini, however, if you are concerned about the carbs in the dish you can cut it back to just 2 cups.
Spice your beef and zucchini casserole by adding in some red pepper.

🙋🏻 Common Questions

How to Store Ground Beef Zucchini Casserole

You can store your ground beef zucchini casserole in the fridge for up to 4 days in a covered container.

Is this a Keto Ground Beef Casserole?

Yes! Just be sure to buy whole fat sour cream and cream cheese to keep carbs low. You can back the amount of sour cream and cream cheese if you need to to accommodate macros for the day. Shredding your own cheese from a block will keep the cheddar cheese at 0 carbs (packaged cheese adds starch (and hidden carbs) to prevent it from sticking).

Worchestershire sauce has a tiny amount of sugar and 1 carb per serving. You can swap the Worchestershire sauce with coconut aminos if you’re strict keto or are following a gluten-free lifestyle.

When prepared as directed, each serving will yield you 7 net carbs per serving. The entire dish contains 6 servings.

What to Serve with Ground Beef Zucchini Casserole?

Ground beef zucchini casserole is a one-dish meal, but if you prefer to add a little something extra to the plate try these options:

Side salad
Broccoli salad
Baked radishes
Pan fried asparagus
Rolls (if you aren’t low carb or gluten free)
