Sausage Pizza Au Gratin Potato Casserole - A delightful fusion of pizza and potatoes

Today, we’re diving into a simple yet profoundly satisfying casserole recipe that elegantly combines two of the most beloved food groups: the vibrant flavors of pizza and the hearty comfort of potatoes. When these two culinary giants come together, something truly magical happens, resulting in a dish that feels both familiar and exciting. This casserole brings them together, all snuggled up and cozy, promising a mouthful of flavor with every bite.

A Family Favorite: The Irresistible Charm of Pizza and Potatoes

While I don’t have children of my own, I can confidently say that this casserole will be an absolute hit with the kiddos – and adults alike! Just the mere mention of “pizza” and “potatoes” in the same sentence is usually enough to get anyone running to the dinner table. It’s a guaranteed crowd-pleaser, making it perfect for busy weeknights, casual gatherings, or any occasion when you need a comforting, hearty meal.

One of my favorite fall side dishes has always been creamy, cheesy au gratin potatoes. I took that beloved concept and infused it with the exciting flavors of a classic pizza, transforming it from a mere side dish into a robust and incredibly delicious main course. Think of it as everything you adore about a piping hot slice of pizza, but with the added luxurious texture of tender, cheese-laden potatoes. It’s truly a celebration of comfort food at its finest, delivering warmth and satisfaction in every forkful.

What makes this casserole so special is its incredible depth of flavor and texture. We’re talking about perfectly seasoned sausage, sautéed vegetables, savory pizza sauce, and an abundance of melted cheese, all layered with perfectly cooked potatoes. Each component contributes to a symphony of tastes that will leave you craving more. This dish manages to capture the essence of a truly indulgent pizza while providing the substantial, homey feel of a potato gratin.

The Perfect Ingredients for a Perfect Casserole

To create this culinary masterpiece, I carefully selected my favorite pizza toppings and combined them into a hearty, flavorful mixture. This blend truly tastes just like you’re enjoying a generous slice of pizza, rich with savory toppings and dripping with extra melted cheese. The star players in this medley include spicy ground hot Italian sausage, earthy baby Portobello mushrooms, sweet onions, and crisp green bell peppers. These ingredients are sautéed to perfection, allowing their flavors to meld and intensify.

But what truly elevates this casserole is the choice of potatoes. I paired these delightful pizza-inspired toppings with Idaho® red potatoes. There’s a specific reason for this selection: red potatoes boast a high moisture center and a waxy exterior, which allows them to hold their shape beautifully. This characteristic is particularly important when they are pan-fried and subsequently baked within the pizza sauce mixture. Unlike some starchier potato varieties that might become mushy, red potatoes maintain a pleasant firmness and texture even after the casserole has been thoroughly baked. This ensures every bite offers a satisfying contrast between the tender potato and the other flavorful components.

Beyond the primary ingredients, the seasoning plays a crucial role. Minced garlic adds an aromatic depth, while a touch of red pepper flakes introduces a subtle, delightful heat that complements the Italian sausage. Dried Italian seasoning ties all the “pizza” flavors together, creating a cohesive and mouthwatering profile. And, of course, no pizza-inspired dish is complete without ample amounts of cheese – a generous blend of grated Parmesan and luscious mozzarella ensures that signature cheesy pull and rich flavor throughout the casserole.

Sausage Pizza Au Gratin Potato Casserole

This easy, comforting casserole combines savory Italian sausage and classic pizza toppings with tender au gratin potatoes and a blend of cheeses. A perfect hearty main dish for any family meal!

Yield: 1 (9-inch-by-13-inch) casserole

Total Time: 1 hour 15 minutes

Prep Time: 15 minutes

Cook Time: 1 hour

Ingredients:

  • 1 pound ground hot Italian sausage
  • 3 tablespoons olive oil, divided
  • 8 ounces sliced baby Portobello mushrooms
  • 5 red potatoes, cut into ½-inch cubes (about 5 cups)
  • 1 large onion, chopped
  • 1 green pepper, chopped
  • 2 cloves garlic, minced
  • 1 teaspoon red pepper flakes
  • 1/2 teaspoon dried Italian seasoning
  • 1 (28-ounce) can pizza sauce
  • 1/4 cup grated Parmesan cheese
  • 2 cups mozzarella cheese, divided
  • 1/4 cup chopped parsley for garnish
  • Salt and pepper to taste

Directions:

  1. Preheat oven to 350 degrees F (175°C). Lightly grease a 9-inch-by-13-inch casserole dish.
  2. Heat a large skillet over medium-high heat. Add the sausage to the pan and cook, breaking up the meat with a spoon as you go along, until it is thoroughly browned, approximately 7-10 minutes. Using a slotted spoon, transfer the cooked sausage to your prepared casserole dish, leaving any rendered fat in the skillet.
  3. Add 1 tablespoon of olive oil to the same pan (if needed, or use the sausage drippings). Stir in the sliced baby Portobello mushrooms. Continue to cook, stirring occasionally, until the mushrooms are tender and beautifully browned, about 5 minutes. To avoid making them watery, refrain from seasoning the mushrooms with salt until the very end of this cooking process. Transfer the browned mushrooms to the casserole dish with the sausage.
  4. Add the remaining 2 tablespoons of olive oil to the pan. Stir in the cubed red potatoes. Season generously with a pinch of salt and pepper. Cook, stirring occasionally, for about 12 minutes, allowing the potatoes to start softening and develop a golden crust.
  5. Add the chopped onion, green pepper, minced garlic, and red pepper flakes to the pan with the potatoes; stir well to combine all ingredients. Continue to cook, stirring often, until the potatoes are fork-tender and the vegetables have softened, which should take approximately 10 additional minutes.
  6. Stir in the dried Italian seasoning, the entire can of pizza sauce, grated Parmesan cheese, and 1 cup of the mozzarella cheese. Continue to cook for about 3 minutes, allowing the sauce to heat through and the cheese to begin melting into the mixture. Season with additional salt and pepper to taste, adjusting to your preference.
  7. Carefully transfer the potato and pizza sauce mixture to the prepared casserole dish containing the sausage and mushrooms; stir everything gently to ensure an even distribution of ingredients. Top the casserole generously with the remaining 1 cup of mozzarella cheese.
  8. Bake the casserole in the preheated oven for 30 minutes, uncovered, or until the cheese is melted, bubbly, and lightly golden brown. For an extra touch, you can sprinkle with fresh chopped parsley before serving, if desired. Let it rest for a few minutes before serving to allow the flavors to set.

Tips for Success and Delicious Variations

To ensure your Sausage Pizza Au Gratin Potato Casserole is always a showstopper, here are a few tips and ideas for customization:

  • Potato Prep: Ensure your potatoes are cut into uniform ½-inch cubes for even cooking. Red potatoes are highly recommended for their texture, but waxy yellow or Yukon Gold potatoes can also work if red ones aren’t available. Avoid starchy Russets as they tend to fall apart.
  • Sausage Swap: If hot Italian sausage is too spicy for your preference or your family, feel free to use mild Italian sausage, ground turkey sausage, or even seasoned ground beef. Adjust the red pepper flakes accordingly.
  • Veggie Boost: Don’t limit yourself to just mushrooms, onions, and green peppers! Consider adding other pizza-friendly vegetables like black olives, sliced bell peppers of different colors, spinach (wilting it in the pan before adding to the mix), or even finely diced zucchini.
  • Cheese Choices: While mozzarella and Parmesan are classic, experiment with other cheeses like provolone, cheddar, or a smoky Gouda for a different flavor profile. A mix of cheeses can add complexity.
  • Crispy Topping: For an extra layer of texture, consider sprinkling a mix of breadcrumbs and a little melted butter over the top cheese layer during the last 10-15 minutes of baking.
  • Make Ahead: You can prepare the sausage and potato mixture (steps 2-6) a day in advance, store it covered in the refrigerator, and assemble and bake it just before serving. You might need to add an extra 5-10 minutes to the baking time if starting from cold.

Serving Suggestions and Storage

This hearty casserole is a complete meal in itself, but it pairs wonderfully with a few simple sides:

  • A crisp, green side salad with a light vinaigrette to cut through the richness.
  • Warm garlic bread or crusty Italian bread for dipping into any extra sauce.
  • Steamed green beans or broccoli for added nutrition.

Storing Leftovers: Any leftover casserole can be stored in an airtight container in the refrigerator for up to 3-4 days. For reheating, individual portions can be warmed in the microwave, or the entire casserole can be gently reheated in an oven at 300°F (150°C) until warmed through, covering it with foil to prevent the top from browning too much. This casserole also freezes well for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
