Keto Philly Cheesesteak Casserole Ingredients • Gather your essentials for this delightful casserole that’ll satisfy your cravings without the carbs. For the Meat Ground Beef – A main protein source providing richness; substitute with ground turkey or chicken for a leaner option. Thinly Sliced Ribeye (or Flank Steak) – Adds depth and chewiness; replace with another beef cut or omit for a vegetarian version. For the Vegetables Onion – Provides sweetness and flavor; use shallots for a milder taste. Green Bell Pepper – Contributes crunch and freshness; any bell pepper variety works—red or yellow add sweetness. Mushrooms – Adds umami and texture; substitute with zucchini or spinach for a veggie boost. Garlic – Enhances overall flavor; can use garlic powder in a pinch. For the Flavor Base Worcestershire Sauce – Offers depth to the beef flavor; replace with soy sauce for a different flavor profile. Italian Seasoning – Adds herbal notes; use fresh herbs or omit based on preference. For the Creaminess Cream Cheese – Creates a creamy, rich base; substitute with sour cream for tanginess or use dairy-free cream cheese for a vegan version. Shredded Provolone Cheese – Melts beautifully for a topping; swap for mozzarella or Monterey Jack. Shredded Mozzarella Cheese – Offers stretchy, gooey texture; can replace with cheddar for a sharper flavor. For Cooking Olive Oil – Used for sautéing; replace with avocado oil for high heat cooking. Step‑by‑Step Instructions for Keto Philly Cheesesteak Casserole Step 1: Preheat the Oven Begin your culinary adventure by preheating the oven to 375°F (190°C). This will ensure a perfectly baked Keto Philly Cheesesteak Casserole with a bubbling cheese topping. While the oven heats up, gather your ingredients and prep your workspace for an efficient cooking experience. Step 2: Sauté the Vegetables In a large skillet, heat a drizzle of olive oil over medium heat. Add in the chopped onions and green bell peppers, sautéing them for about 5 minutes until they become tender and aromatic. Stir in the minced garlic and let it cook for an additional minute, just until fragrant. Once done, remove the vegetables from the skillet and set aside. Step 3: Brown the Ground Beef In the same skillet, add the ground beef and cook over medium-high heat for approximately 6-8 minutes. Use a spatula to break up the meat into smaller pieces as it browns. Cook until it’s no longer pink and resembles a deep brown color, ensuring to drain any excess grease to keep the Keto Philly Cheesesteak Casserole from becoming oily. Step 4: Incorporate the Ribeye and Seasonings Next, stir in the thinly sliced ribeye, Worcestershire sauce, Italian seasoning, and season with salt and pepper. Allow everything to cook together for about 2-3 minutes, just until the beef is tender and fully cooked. You want those savory flavors to meld beautifully, making your casserole delightful. Step 5: Combine with the Vegetables Gently fold the sautéed onions, bell peppers, and any mushrooms you’ve chosen into the beef mixture. This step really enhances the flavor profile of your Keto Philly Cheesesteak Casserole, allowing the ingredients to marry together. Cook for another minute to warm everything through and combine well. Step 6: Melt in the Cream Cheese Reduce the skillet’s heat to low and add the cream cheese. Stir continuously until it melts completely and forms a creamy mixture with the beef and veggies. This rich blend is what makes your casserole so comforting and decadent. It should look creamy and inviting! Step 7: Transfer to a Baking Dish Carefully pour the beef and vegetable mixture into a greased 9×13 inch baking dish, spreading it out evenly. This is where the magic of the Keto Philly Cheesesteak Casserole happens! Top it generously with both provolone and mozzarella cheese, ensuring every bite will be deliciously cheesy. Step 8: Bake to Perfection Place the baking dish in your preheated oven and bake for about 20 minutes. Keep an eye on it, as you want the cheese to become bubbly and golden brown. The enticing aroma will fill your kitchen, giving a hint of the delicious meal that awaits you. Step 9: Cool and Serve Once baked, carefully remove the casserole from the oven and let it cool slightly for about 5-10 minutes. This will help it set up a bit and make serving easier. When ready, garnish with freshly chopped parsley for a pop of color and flavor, and dive into this warm, cheesy wonder!
