Ingredients:

For this WW-friendly Philly Cheesesteak Casserole, you’ll be using lean beef, a variety of vegetables, and light cheese options to keep the SmartPoints low without sacrificing flavor. Here’s what you’ll need:

For the Casserole:

  • 1 pound lean sirloin steak, thinly sliced (or ground sirloin)
  • 1 tablespoon olive oil (divided)
  • 1 medium onion, thinly sliced
  • 1 red bell pepper, thinly sliced
  • 1 green bell pepper, thinly sliced
  • 2 cloves garlic, minced
  • 1 cup mushrooms, sliced (optional but recommended)
  • 1/2 cup fat-free beef broth (or vegetable broth for a milder taste)
  • 2 cups cauliflower rice (fresh or frozen)
  • 1/2 cup reduced-fat shredded provolone cheese
  • 1/4 cup reduced-fat shredded mozzarella cheese
  • 1/4 teaspoon ground black pepper
  • 1/4 teaspoon paprika
  • 1/4 teaspoon garlic powder
  • Salt to taste (optional)

For the Sauce:

  • 1/4 cup fat-free cream cheese (or nonfat Greek yogurt for a tangy flavor)
  • 1/4 cup fat-free sour cream
  • 2 tablespoons Dijon mustard
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon hot sauce (optional for a little heat)

Instructions:

Step 1: Prepare the Ingredients Begin by prepping all the vegetables and ingredients for the casserole. Thinly slice the onion, bell peppers, and mushrooms (if using). Mince the garlic. If you’re using fresh cauliflower rice, break it down into smaller pieces using a food processor or a knife.

Step 2: Cook the Sirloin Steak In a large skillet, heat 1/2 tablespoon of olive oil over medium-high heat. Add the thinly sliced sirloin steak (or ground sirloin) to the pan. Season with a pinch of salt and black pepper. Cook the meat until it’s browned on all sides and cooked through, about 5-7 minutes. Once done, transfer the beef to a plate and set aside.

Step 3: Sauté the Vegetables In the same skillet, add the remaining 1/2 tablespoon of olive oil over medium heat. Add the sliced onion, red and green bell peppers, and mushrooms (if using). Cook the vegetables until they begin to soften and caramelize, about 8 minutes. Add the minced garlic and cook for another 1 minute, until fragrant. Pour in the beef broth, scraping up any browned bits from the bottom of the skillet.

Step 4: Combine the Meat and Vegetables Return the cooked beef to the skillet with the vegetables. Stir everything together and season with paprika, garlic powder, and additional salt if necessary. Let the mixture simmer for another 3-4 minutes, allowing the flavors to meld together.

Step 5: Prepare the Sauce While the meat and vegetables are simmering, in a separate bowl, combine the fat-free cream cheese, fat-free sour cream, Dijon mustard, Worcestershire sauce, and hot sauce (if using). Stir until smooth and creamy. This sauce will give the casserole its signature rich, cheesy flavor without adding excess calories or SmartPoints.

Step 6: Assemble the Casserole Preheat your oven to 375°F (190°C). In a large baking dish (about 9×13 inches), spread out the cauliflower rice evenly as the base layer. Top the cauliflower rice with the meat and vegetable mixture from the skillet. Spread the sauce evenly over the top of the casserole, ensuring every bite is coated with that creamy goodness.

Step 7: Add the Cheese Sprinkle the reduced-fat provolone and mozzarella cheese over the casserole, distributing evenly. The cheese will melt and form a golden, bubbly layer as it bakes.

Step 8: Bake the Casserole Place the casserole in the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly. If you like your cheese a little crispier, broil for an additional 2-3 minutes at the end of the cooking time.

Step 9: Serve and Enjoy Once your WW Philly Cheesesteak Casserole is done, remove it from the oven and let it rest for a few minutes before serving. Cut it into squares and serve with a side of roasted veggies or a fresh salad for a complete meal.

Tips for Making this WW Philly Cheesesteak Casserole Even Better:

  1. Add More Veggies: Feel free to load up your casserole with extra veggies like spinach, zucchini, or even tomatoes for an added boost of nutrients. These will add minimal SmartPoints while enhancing the flavor and texture.
  2. Swap the Cauliflower Rice: If you’re not a fan of cauliflower rice, you can substitute with regular cooked brown rice or quinoa. Keep in mind that this may increase the SmartPoints value.
  3. Lean Protein Alternatives: For a lighter version, you can use lean ground turkey or chicken breast instead of the sirloin steak. These options will reduce the overall fat content and SmartPoints.
  4. Make Ahead Option: This casserole can be made ahead of time! Assemble the casserole, then cover it tightly and store it in the refrigerator for up to 24 hours before baking. This makes it a great option for meal prep.
  5. Vegan Version: To make this dish vegan, substitute the cream cheese and sour cream with dairy-free versions, and use plant-based cheese alternatives. Additionally, you can swap the sirloin for a plant-based protein like tempeh or tofu.
