Step-by-Step Instructions

🔥 Step 1: Prep the Beef and Vegetables

1️⃣ Start by dicing your sirloin steak into small bite-sized pieces. You want it to cook quickly and evenly, so cutting it into uniform chunks is key.

2️⃣ Heat olive oil in a large skillet over medium heat. Add the diced steak and sauté for 4-5 minutes until the beef is browned.

3️⃣ Next, add the diced onion and bell peppers to the skillet. Stir occasionally and cook for another 3-4 minutes until they’re softened and fragrant.

💡 Pro Tip: For a smoky flavor, try adding a dash of smoked paprika while sautéing the beef and vegetables!

🧀 Step 2: Prepare the Casserole Base

1️⃣ In a medium bowl, combine the frozen hash browns, garlic powder, salt, and pepper. Pour in the melted butter and mix everything well.

2️⃣ Spread the hash brown mixture evenly into the bottom of a greased casserole dish. Press it down gently to form a firm base.

💡 Pro Tip: You can use cubed bread instead of hash browns for a more traditional casserole base!

---

🔥 Step 3: Add the Cheesy Layers

1️⃣ In a separate bowl, mix the cream cheese, sour cream, and shredded cheeses (provolone and mozzarella). Stir until smooth and creamy.

2️⃣ Spread the cheese mixture over the hash brown base, making sure it’s evenly distributed.

💡 Pro Tip: For an extra cheesy casserole, add more cheese on top before baking!

---

🥩 Step 4: Assemble the Casserole

1️⃣ Now, take the cooked beef and vegetable mixture and spread it evenly over the cheese layer.

2️⃣ Press everything down gently to ensure that all layers are compact and the cheese melts perfectly when baking.

💡 Pro Tip: If you want a spicy kick, sprinkle some red pepper flakes over the top!

---

🔥 Step 5: Bake to Perfection

1️⃣ Preheat your oven to 375°F (190°C).

2️⃣ Cover the casserole dish with foil and bake for 25 minutes. This will allow the flavors to meld together and the cheese to melt beautifully.

3️⃣ After 25 minutes, remove the foil and bake for an additional 10 minutes to let the top get golden and crispy.

💡 Pro Tip: If you like your casserole extra crispy, broil it for the last 2 minutes!
