How to Make Sausage Potato Casserole
Making this casserole couldn’t be easier! Follow these simple steps:
1. Prep the oven and dish. Preheat the oven to 375°F. Grease a 9×13-inch baking dish.
2. Cook the sausage. In a large skillet over medium-high heat, cook the sausage until browned, breaking it up as it cooks. Transfer to a plate.
3. Sauté the vegetables. In the same skillet, sauté the onion and bell pepper until softened, about 5 minutes. Stir in the garlic and cook 1 minute more. Remove from heat.
4. Layer the potatoes and sausage. Arrange half of the sliced potatoes in the prepared baking dish. Top with half of the sausage and vegetable mixture.
5. Make the sauce. In a bowl, whisk together the soup, milk, thyme, salt, pepper, and red pepper flakes. Pour half of the soup mixture over the potatoes and sausage.
6. Repeat the layers. Repeat the layers with the remaining potatoes, sausage mixture, and soup mixture. Cover the dish tightly with foil.
7. Bake the casserole. Bake for 1 hour, until the potatoes are tender. Remove the foil, and sprinkle with cheddar cheese.
8. Melt the cheese. Return to the oven and bake uncovered for 10 more minutes, until the cheese is melted and bubbly. Let stand 10 minutes before serving.
9. Garnish and serve. Sprinkle with the remaining cheese and sliced green onions. Serve hot and enjoy!
Tips For the Best Sausage Potato Casserole
This casserole is foolproof, but these tips make it even more amazing!
- Pick your potatoes wisely. Red potatoes work best in this casserole for their size and consistency. They hold their shape well and allow the cheesy sauce to bind everything together.
- Get ahead of yourself. Chop all the vegetables in advance and refrigerate until ready to use. Cut them to similar sizes so they cook evenly.
- Make a sausage swap. For a different flavor profile, swap smoked sausage for Italian sausage, chicken/turkey sausage, kielbasa, or ham.
- Take a shortcut. Assemble the casserole in a slow cooker and cook on low for 7-8 hours for an easy, hands-off approach.
- Be super cheesy. Try Velveeta, Gruyere, or a mix for extra cheesy goodness. Add some on top during the last 10-15 minutes of baking.
- Try new variations. This casserole is very adaptable. You can use different vegetables like mushrooms, peppers, or zucchini.
How to Store
Follow these steps to store leftover casserole to keep it fresh:
To Store: Keep leftovers in an air-tight container in the refrigerator for up to 4 days. Store individual portions separately for easy reheating later.
To Freeze: Wrap the cooled casserole tightly in plastic wrap followed by foil and freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
To Reheat: Reheat individual portions in the microwave until warmed through. Or, place the entire casserole covered with foil in a 350°F oven for 20-30 minutes. Add a small amount of water or broth before reheating to prevent drying out.
