🛒 Ingredients You’ll Need:

Let’s gather up what you’ll need for this casserole. Most of it’s probably already in your kitchen:

• 1 pound ground beef

• 3 ounces cream cheese – softened to melt faster

• 1/2 cup beef broth – adds depth to the sauce

• 1/2 cup heavy whipping cream – for that creamy, dreamy texture

• 2 tsp Bragg’s Aminos (or soy sauce) – for a little umami kick

• 1 teaspoon garlic powder

• 1/2 teaspoon onion powder

• 2 cans green beans, drained – fresh or frozen work too

• 3/4 cup cheddar cheese

• 3/4 cup mozzarella cheese

• 1/2 teaspoon salt

• 1/2 teaspoon pepper

🍳 Equipment:

You don’t need a fancy kitchen to make this meal, just:

• 10.25” Cast Iron Skillet (or any oven-safe skillet)

• A wooden spoon

• A good appetite 😋

🔥 Let’s Get Cookin’ – Step-by-Step Instructions:

1. Preheat and Brown

Start by preheating your oven to 350°F (175°C). While that’s happening, heat your cast iron skillet over medium heat. Add in the ground beef and cook it until it’s nicely browned.
Once browned, drain off any excess grease—you want flavor, not an oil slick.

2. Cream It Up

Time to make things saucy. Add your softened cream cheese to the skillet. Stir it into the beef until it melts and becomes one with the meat. Oh yeah, now we’re talking creamy comfort.

3. Sauce it Like a Pro

Pour in the beef broth, heavy whipping cream, and Bragg’s Aminos (or soy sauce). Add your garlic powder, onion powder, salt, and pepper. Stir it all together.
Crank the heat up just a bit and bring that beauty to a low boil, then reduce to a simmer. Let it bubble gently until the sauce thickens—it should coat the back of a spoon. This part is where the magic starts to happen.

4. Add the Veggies

Stir in your drained green beans. They’ll soak up some of that creamy flavor while bringing their own crunch and freshness to the party.

5. Say Cheese!

Sprinkle the top with cheddar cheese and mozzarella cheese. The mix of both gives you that perfect cheesy pull and golden-brown top.

6. Bake it to Bubbly Goodness

Pop the skillet into your preheated oven and bake for about 25 minutes, or until the cheese is melted, bubbly, and slightly golden.

7. Rest and Serve

Let it rest for 5 minutes before serving—this helps everything settle and makes it easier to dish up.

💡 Pro Tips from the Chef’s Apron

• Don’t skip the simmer. Letting the sauce reduce just a little adds serious flavor.

• Go fresh when you can. If using fresh green beans, blanch them for 2–3 minutes first so they stay crisp-tender.

• Cheese choices: Feel free to mix in some pepper jack or gouda for a fun flavor twist.

• Drain that grease! It’s tempting to skip this step when you’re hangry, but trust me—your casserole will thank you.

🧊 Storage & Make-Ahead Tips

This casserole was practically made for leftovers and meal prep:

🍱 Refrigeration

Let the casserole cool completely, then store it in an airtight container in the fridge. It’ll keep well for 3–4 days. Just reheat and enjoy!

❄️ Freezing

Wrap individual portions or the entire casserole tightly in plastic wrap and aluminum foil. It freezes beautifully for up to 3 months. Thaw in the fridge overnight before reheating.

🔁 Reheating

Pop it in a 325°F oven for 25–30 minutes to bring it back to its former glory.
For smaller portions, the microwave works too—just use 30-second intervals, stirring in between.

🔄 Variations to Make It Your Own

You know I love giving you options! Here are a few tasty twists:

🥩 Switch Up the Protein

Swap out the ground beef for ground turkey, chicken, Italian sausage, or even pork.
(For poultry, use chicken broth instead of beef.)

🥦 Add More Veggies

Try tossing in some zucchini slices, mushrooms, bell peppers, cauliflower rice, or broccoli florets for added nutrition and texture.

🌶️ Go Tex-Mex

Add a tablespoon of taco seasoning, some diced jalapeños, and maybe a little sour cream and salsa on top for a spicy south-of-the-border twist.

🥓 Top with Bacon

Because… do we even need a reason? Sprinkle on crispy bacon crumbles before baking for a smoky, salty kick.
