Key Ingredients

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Italian Sausage: I prefer using high-quality mild or hot Italian pork sausage links. They release rich, savory fat during roasting, which seasons the surrounding vegetables perfectly.

Bell Peppers: Green and red bell peppers add a gorgeous pop of color and natural sweetness. They soften beautifully in the oven, creating a wonderful melt-in-your-mouth texture.

Yellow Onions: Thickly sliced yellow onions become incredibly sweet and beautifully caramelized under high heat. They provide a savory backbone that ties all the individual elements together.

Russet Potatoes: I love using russet or Yukon Gold potatoes for their starchy, fluffy interiors. They absorb the savory juices while their skins turn delightfully crispy.

Olive Oil: A generous drizzle of extra virgin olive oil helps the vegetables roast evenly. Additionally, it ensures the dried seasonings stick to every single piece.

Italian Seasoning: This classic blend of dried herbs adds an authentic, rustic Italian flair. It elevates the simple ingredients into a truly restaurant-worthy bake.

How to Make Sausage, Peppers, Onions, and Potato Bake

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

1. Preheat your oven to 400°F (200°C) and lightly grease a large baking dish with olive oil.
2. Cut the potatoes, peppers, and onions into thick, even slices to ensure they cook at the same rate.
3. Toss the sliced vegetables with olive oil, minced garlic, dried Italian seasoning, salt, and black pepper.
4. Arrange the seasoned vegetables in an even layer across the prepared baking dish.
5. Slice the Italian sausage links into third-size pieces and nestle them deeply into the vegetable mixture.
6. Bake uncovered at 400°F (200°C) for 40 to 45 minutes until the potatoes are tender and golden.
7. Stir the mixture halfway through the cooking time to ensure the sausages brown evenly on all sides.

Pro Tip: Cut your potatoes into relatively thin slices so they cook fully in the same time it takes the peppers to soften.

Common Mistakes to Avoid

• Crowding the pan too tightly, which steams the vegetables instead of roasting them beautifully.
• Slicing the onions too thin, which causes them to burn before the potatoes fully soften.
• Skipping the halfway stir, which prevents the sausage pieces from browning nicely on all sides.

Required Equipment

• 9x13 Baking Dish — provides ample surface area for even roasting and beautiful browning.
• Sharp Chef's Knife — allows you to slice through tough potatoes and peppers cleanly.
• Large Mixing Bowl — makes tossing the vegetables with oil and spices incredibly easy.

Caleb's Recipe Tips

• Poke the sausage pieces with a fork before roasting to release their flavorful juices.
• Toss in a pinch of red pepper flakes if you enjoy a spicy kick.
• Use a mix of red, yellow, and green bell peppers for a beautiful visual presentation.
• Roast on the bottom oven rack during the last ten minutes for extra-crisp potatoes.
• Sprinkle freshly grated Parmesan cheese over the hot dish immediately after removing it from the oven.

Storage Instructions

Store any leftover bake in an airtight container in the refrigerator for up to four days. However, I do not recommend freezing this dish because the potatoes will lose their pleasant texture. When you are ready to eat, simply reheat individual portions in a hot skillet over medium heat. Alternatively, warm them in the oven at 350°F (175°C) until the sausage is heated completely through.
