I love starting with lean ground beef or chicken because it keeps the dish healthy and tasty. Diced onion and green bell pepper add sweetness and crunch. Sliced mushrooms bring an earthy flavor, while minced garlic gives it a nice kick. Low-fat cream cheese and Greek yogurt make the dish creamy without adding too many calories. I use cooked quinoa for a protein boost and a lovely texture. Shredded provolone cheese finishes this dish beautifully. It melts to create a gooey, comforting layer. I also add Worcestershire sauce to deepen the flavors, along with salt and pepper for seasoning. A drizzle of olive oil helps to sauté the veggies perfectly. To bring it all together, I garnish with fresh parsley. It adds a pop of color and freshness. Each ingredient plays a role in making this casserole both tasty and satisfying. {{ingredient_image_2}} First, preheat your oven to 375°F (190°C). This step is crucial for even baking. While the oven warms up, grease a 9x13-inch baking dish. Use olive oil or cooking spray to keep it non-stick. In a large skillet, heat the olive oil over medium heat. Add the diced onion and green bell pepper. Cook them for about 3-4 minutes. You want them soft and fragrant. Next, toss in the sliced mushrooms and minced garlic. Cook for another 3 minutes. The mushrooms should release their juices and become tender. Now, add the lean ground beef or chicken to the skillet. Cook the meat until it turns brown, breaking it into small pieces. This should take about 5-7 minutes. Season the mixture with Worcestershire sauce, salt, and pepper. Taste it to ensure the flavors are just right. In a large mixing bowl, mix the cooked quinoa, low-fat cream cheese, and Greek yogurt. Blend until it forms a smooth mixture. Then, add the sautéed meat and vegetable mix to the bowl. Stir gently until everything is well combined. Transfer the mixture into the greased baking dish. Spread it evenly for uniform baking. Top with shredded provolone cheese. Place the casserole in the preheated oven. Bake for 25-30 minutes until the cheese melts and turns golden. After baking, let it cool for a few minutes. Garnish with chopped parsley for a fresh touch. To ensure even cooking, spread the mixture in the baking dish evenly. This helps the heat reach all areas. Stir the casserole halfway through baking for best results. For cheese melting, use shredded provolone. Shredded cheese melts faster and gives a nice texture. Sprinkle it on top just before baking for that perfect golden finish. You can try alternative proteins like turkey or plant-based options. Ground turkey lowers fat while packing protein. To add fresh vegetables, consider spinach or zucchini. These options boost flavor and nutrition. They also add color, making your dish more appealing. Serve the casserole straight from the baking dish for a rustic feel. It enhances the homey vibe of the meal. You can also add garnishes like chopped parsley for a fresh touch. If you want some spice, drizzle sriracha or hot sauce on individual plates. This adds fun and excitement to each serving! Pro Tips Choose the Right Meat: Opt for lean ground beef or chicken to keep the casserole healthier without sacrificing flavor. Cook Quinoa Properly: Ensure the quinoa is fully cooked and fluffed before mixing it into the casserole for the best texture. Customize with Veggies: Feel free to add or substitute other vegetables like spinach or zucchini for added nutrition and flavor. Let it Rest: After baking, allow the casserole to sit for a few minutes before serving; this helps the layers set and makes slicing easier. {{image_4}} For a vegetarian version of this casserole, you can use plant-based protein. Options like lentils or tempeh work well. You can also add more vegetables. Try zucchini, spinach, or even eggplant for added flavor and nutrition. These swaps keep the dish hearty and satisfying without meat. If you like things hot, add jalapeños or hot sauce. Just chop jalapeños and mix them into the meat and veggie mix. You can also drizzle hot sauce on top before serving. This addition gives the dish a nice kick and makes it extra flavorful. To make a low-carb version, you can substitute quinoa with cauliflower rice. This keeps the dish light and cuts down on carbs. Also, consider using dairy-free cheese alternatives. There are many great options on the market that melt well. These changes make the casserole friendly for those watching their carb intake. To store leftover high-protein Philly cheesesteak casserole, let it cool first. Place it in an airtight container. This helps keep it fresh. You can store it in the fridge for up to 3 to 4 days. If you want it to last longer, consider freezing it. Wrapped tightly, it can stay good for about 2 to 3 months. When you are ready to enjoy the casserole again, use the oven for reheating. Preheat the oven to 350°F (175°C). Place the casserole in a baking dish. Cover it with foil to keep it moist. Heat for about 20-25 minutes or until it's hot throughout. This method helps keep the cheese melty and the texture nice. You can also use the microwave, but it may change the texture. Heat in short bursts, stirring in between to keep it even. Enjoy your delicious leftovers! Yes, you can use other cheeses. Cheddar, mozzarella, or gouda work well too. Each cheese adds a unique flavor. If you want a sharper taste, try sharp cheddar. For a creamier texture, mozzarella is perfect. Always choose a cheese that melts well to get that tasty, gooey texture. To make this casserole gluten-free, swap cooked quinoa for gluten-free grains. You can use brown rice or gluten-free pasta. Also, check that your Worcestershire sauce is gluten-free. Many brands offer gluten-free options, so read the label.
