Italian Sausage and Peppers in the Oven
Jump to Recipe Yum

Italian sausage and peppers in the oven makes for such an easy meal. Once you have your vegetables sliced, and everything on the tray, the only other thing you need to do is turn it all halfway through cooking!

I love that this meal is naturally low-carb, so there is no need for substitutions or hard-to-find ingredients.

What is Italian sausage?

Italian sausage is seasoned ground pork in a shell casing. The links are typically 6 inches long. What sets them apart is that they usually contain fennel seeds.

Is Italian sausage good for you?

This really depends on the brand you buy. Pasture-raised pork has a higher nutritional value than conventionally-raised pork. Also, some brands contain a lot of salt, so make sure to check the label.

Is sweet Italian sausage ok for PCOS?

The short answer is no. Sweet Italian sausage normally has some form of sugar added.

Does the fennel in Italian sausage make a difference?

Fennel seeds can aid digestion. It’s so interesting that foods which taste good together (pork and fennel) improve the absorption of nutrients of each other when eaten together.

Why cook sausage and pepper in the oven, and not on the stove or in the slow cooker?

You can make sausage and peppers in a skillet or in the slow cooker but the oven is my favorite because it requires the least amount of hands-on time. The slow cooker takes ages and you don’t get that nice browning on the sausages. Another option is in a skillet but that requires watching everything very closely so they don’t burn.

Notes on ingredients

Mild vs. Spicy vs. Sweet Italian Sausage

Italian sausage comes in three different types: mild, spicy and sweet. You should avoid the sweet kind as this will contain sugar in some form. As for mild or spicy, both are good, it’s just a matter of personal preference!

Difference between Red, Orange and Green Bell Peppers

Red peppers are the best because they have been on the vine the longest and so, have more nutrients. Green peppers are picked before they have had a chance to turn red. This is why green peppers are often cheaper. They can be harvested sooner. Yellow and orange peppers are picked on their way to turning red.

Which Type of Onion to Use

The recipe lists yellow onion but white onion and red onion work too.

Additions and Substitutions

  • Pork sausage can be substituted for turkey or chicken sausage. You will need to drizzle these with olive oil before they go in the oven. Turkey does not contain as much fat as pork and they might dry out.
  • Garlic makes a great addition to this meal. I like to add entire cloves because they become sweet when roasted in the oven.
  • Red chili flakes add an extra level of spice. Sprinkle 1/2 tsp on peppers when you have arranged them on the baking sheet.
