Ingredients for Sizzling Keto Philly Cheesesteak Casserole

Let’s dive into the ingredients that come together to create this mouthwatering Sizzling Keto Philly Cheesesteak Casserole! Each one is vital, adding its unique charm to the dish. Don’t worry, the precise measurements can be found at the bottom of the article for easy printing!

Ground beef or thinly sliced steak: This is the star of your casserole! Opt for lean ground beef or a tender cut like ribeye for that authentic Philly cheesesteak experience. If you want a meatless version, feel free to swap in some hearty mushrooms.
Bell pepper: A pop of vibrant color and sweetness! You can use green or red peppers based on your preference. Red adds a hint of sweetness, while green delivers a slightly more peppery flavor.
Onion: Diced onions add a wonderful aromatic base to the dish. Yellow onions are my go-to for their sweetness, but feel free to use white onions for a sharper punch.
Garlic: Freshly minced garlic enhances the overall flavor profile, infusing warmth and richness into the casserole. Use more if you’re a garlic lover!
Mushrooms: Sliced mushrooms bring an earthy depth to the dish. Button or cremini mushrooms work well, but you could also add portobellos for a meatier texture.
Heavy cream: The creamy sauce is what makes this casserole comfort food at its best. You can replace it with half-and-half or even coconut cream for a dairy-free option.
Provolone cheese (or mozzarella): A melty layer of provolone offers that authentic cheesesteak flavor. Mozzarella can be a great substitute if provolone isn’t available.
Cheddar cheese: Adding shredded cheddar gives an extra cheesy kick! It’s perfect for creating that golden, bubbly top layer.
Worcestershire sauce: This adds a hint of umami, balancing the richness of the cream and cheese. You can skip it or use a gluten-free version if needed.
Italian seasoning: A delightful blend of herbs ties the flavors together. If you prefer fresh herbs, feel free to use basil or oregano straight from your garden!
Salt and pepper: Always season to taste! These staples elevate the overall flavor.
Olive oil or butter: Used for sautéing, this fat adds richness. Butter will give a delightful taste, but olive oil is a healthier option and works perfectly too.
Fresh parsley (for garnish): A sprinkle of vibrant parsley adds freshness to the top. It’s all about that finishing touch!

How to Make Sizzling Keto Philly Cheesesteak Casserole

Step 1: Preheat and Prepare the Casserole Dish

To kick things off, preheat your oven to 350°F (175°C). This gives the casserole that perfect bubbly finish. While that’s warming up, grab a 9×13 inch casserole dish and grease it with olive oil or non-stick spray. This little step helps to prevent your delicious creation from sticking. Nobody wants a stuck-on mess, right? Trust me, it makes serving and cleanup so much easier!

Step 2: Cook the Beef or Steak

Heat up a large skillet over medium-high heat. Add in a tablespoon of olive oil or butter, then toss in your ground beef or sliced steak. Let it cook for about 5-7 minutes until nicely browned. Don’t forget to season it with salt, pepper, and a splash of Worcestershire sauce. This adds a savory depth, making your flavors sing! Once done, remove the beef from the skillet and set it aside to keep warm. That browning adds so much flavor!

Step 3: Sauté the Vegetables

In the same skillet, you’ll want to add another tablespoon of oil if necessary. Sauté the diced onions and minced garlic for about 2 minutes, or until they become translucent and fragrant. Then, throw in your bell pepper and sliced mushrooms. Cook these colorful veggies for another 5-6 minutes until they’ve softened. The aroma will fill your home, making it feel cozy and warm! These veggies add so much character to your casserole.

Step 4: Combine Ingredients

In a large mixing bowl, take that gorgeous beef you set aside and combine it with the sautéed veggies. Pour in the heavy cream along with your Italian seasoning. Mix everything together well, ensuring that all flavors blend beautifully. You’ll want every bite to be just as tasty as the last! This creamy, savory blend is the heart of your Sizzling Keto Philly Cheesesteak Casserole.

Step 5: Assemble the Casserole

Now it’s time for the fun part! Transfer your flavorful mixture into the greased casserole dish. Spread it out evenly, creating a delicious base. Next, layer on the shredded provolone cheese and follow it up with a sprinkle of shredded cheddar cheese. This cheesy goodness is going to melt and form a fantastic crust on top! It’s practically begging to go in the oven.

Step 6: Bake to Perfection

Carefully place the casserole in your preheated oven and let it bake for about 25-30 minutes. Keep an eye on it—you’re looking for the cheese to get bubbly and golden brown. That’s how you know it’s ready to come out! The anticipation builds as you catch whiffs of that sizzling goodness. You’re going to love it!

Step 7: Cool and Garnish

When your casserole is done baking, remove it from the oven and let it cool for a few minutes. This helps the layers settle and makes it easier to slice. Before serving, give it a fresh touch by sprinkling some chopped parsley on top. It makes your dish pop and adds a lovely flavor boost!

Tips for Success

Always let your casserole cool for a few minutes before slicing. This helps it hold its shape!
For extra flavor, try marinating your beef in the Worcestershire sauce for an hour before cooking.
Feel free to double the recipe and freeze half for later. Meal prep made easy!
Experiment with cheese combinations! Adding pepper jack can add a spicy kick!
If you’re low on time, pre-chop your veggies ahead of time.

Equipment Needed

Large Skillet: A heavy-duty skillet is perfect for browning meat and sautéing veggies. If you don’t have one, a frying pan will work too!
Casserole Dish: A 9×13 inch dish is ideal, but any similar-sized oven-safe dish will do.
Mixing Bowl: Use a large bowl for combining ingredients; a sturdy plastic bowl works just as well.
Spatula: A classic spatula is great for mixing and transferring food; a wooden spoon works too!

Variations

Vegetable Medley: Add more veggies like zucchini, spinach, or cherry tomatoes for a colorful twist. They also boost nutrition!
Spicy Option: Toss in some diced jalapeños or a sprinkle of red pepper flakes for a hint of heat. Your taste buds will thank you!
Different Cheeses: Experiment with different cheese blends! Try gouda for a smoky flavor or feta for a tangy punch.
Dairy-Free Version: Swap heavy cream for coconut cream and use dairy-free cheese alternatives to make it completely dairy-free!
Stuffed Peppers: Use this mixture to stuff halved bell peppers instead of making a casserole. Bake until the peppers are tender for a fun presentation!

A side of roasted broccoli or asparagus adds a nice crunch and is low in carbs.
