Ingredients

Bell peppers

You will need three to four bell peppers. Any color will work, so use your favorite combination.

Red, orange, and yellow bell peppers tend to be slightly sweeter, while green peppers have a stronger, more savory flavor. Using several colors also makes the finished dish especially vibrant.

Cut the peppers into strips approximately ¼-inch thick. Avoid cutting them too thin, since very thin strips can become overly soft while roasting.

Onion

One medium onion adds sweetness and savory flavor as it roasts.

Yellow, white, or red onion can all work. Cut it into strips similar in size to the bell peppers so the vegetables cook evenly.

Sausage

This recipe uses four to five links of precooked sausage. Italian sausage is a classic choice, but chicken sausage, turkey sausage, pork sausage, or another favorite variety can also work.

Check the ingredient label when following a particular eating plan. Some sausages contain added sugar, breadcrumbs, gluten, dairy, or other ingredients that may not fit a keto, Paleo, or gluten-free diet.

Because the sausage is already cooked, it only needs to heat through and brown while the vegetables roast.

Avocado oil

Avocado oil helps the peppers, onions, and sausage roast without sticking. It also helps the dried seasonings coat the ingredients evenly.

Olive oil can be substituted when needed.

Seasonings

This recipe uses a simple combination of:

• Dried oregano
• Granulated garlic
• Salt

The seasonings complement the sausage without overpowering it. Because sausage can already be salty, check the label and reduce the added salt slightly when using an especially salty variety.

How to Make Keto Sheet Pan Sausage and Peppers

1. Preheat the oven

Preheat the oven to 400°F.

Line a large rimmed baking sheet with parchment paper for easier cleanup. You can also place the ingredients directly on the baking sheet.

2. Prepare the vegetables

Remove the stems and seeds from the bell peppers, then cut the peppers into strips approximately ¼-inch thick.

Peel the onion and cut it into similarly sized strips.

Keeping the vegetables close to the same thickness will help them roast more evenly.

3. Prepare the sausage

Cut each precooked sausage link in half crosswise.

The sausages can be sliced into smaller pieces after roasting. Leaving them in larger pieces while they cook helps prevent them from drying out.

4. Mix the seasonings

In a small bowl, stir together the avocado oil, dried oregano, granulated garlic, and salt.

Mixing the seasonings with the oil first helps distribute them more evenly throughout the dish.

5. Arrange everything on the sheet pan

Place the bell peppers, onion, and sausage on the prepared baking sheet.

Pour the seasoned oil over everything and toss until the vegetables and sausage are evenly coated.

Spread the ingredients into a single layer. Try not to overcrowd or stack the vegetables, since they will roast better when they have room around them.

6. Roast

Roast for approximately 30 to 35 minutes, or until the peppers and onions are tender and beginning to brown around the edges.

The exact cooking time may vary depending on how thickly the vegetables are cut and how crowded the baking sheet is.

7. Slice and serve

Carefully transfer the sausage to a cutting board and slice it into approximately 1-inch pieces.

Return the sliced sausage to the vegetables, toss everything together, and serve warm.

Tips for the Best Sausage and Peppers

Do not overcrowd the pan

Spread everything into a single layer. If the ingredients are crowded together, the vegetables may steam instead of developing lightly roasted edges.

Use two baking sheets when necessary.

Cut the vegetables evenly

Cut the bell peppers and onion into strips that are similar in thickness. This helps prevent some pieces from becoming overcooked while others remain firm.

Use precooked sausage

The cooking time in this recipe is intended for fully cooked sausage. Raw sausage requires different handling and may need additional cooking time.

Check the package to confirm which type you purchased.

Check the sausage ingredients

Sausage ingredients vary significantly by brand and flavor.

For a keto version, look for sausage without significant added sugar or starchy fillers. For a Paleo or gluten-free version, choose a sausage specifically labeled or formulated for those needs.

Adjust the seasoning carefully

Taste and salt preferences will depend on the sausage. A strongly seasoned sausage may require less added salt than a mild chicken or turkey sausage.
