This sausage and peppers recipe is what I call a weeknight hero dish. It is perfect for those times when you want maximum flavor without filling your sink with pans. Its roots are Italian American but honestly it is now a classic in my own kitchen and there is nothing more comforting than roasted sausage mingling with sweet peppers and onions in one big pan.
I made this first when I had guests coming over unexpectedly and now it shows up in my meal plan every month. It is just so reliable and everyone goes back for seconds.
Ingredients
- Extra virgin olive oil: because it creates a rich base flavor and helps the veggies caramelize well look for one that is single origin for best taste
- Red wine vinegar: because it brightens everything up choose one that is bold and fruity for best results
- Garlic: use cloves that are heavy for their size and free of green sprouts mince them so they disappear into the dish
- Dried oregano: because it brings warmth and earthy flavor look for a fresh aromatic jar not one that has been hiding in your cupboard for years
- Crushed red pepper: for a little heat pick flakes that are deep red for fresher flavor or leave it out if you do not want spice
- Bell peppers: I like a mix of red yellow and orange for color and sweetness choose peppers with shiny unwrinkled skin
- Yellow onion: opt for firm onions that are heavy and have no soft spots cut to match the peppers in size for even roasting
- Kosher salt and freshly ground black pepper: because seasoning as you go brings the whole dish to life
- Italian sausage: I usually go for sweet or hot depending on my mood look for sausages with plump casings and lots of visible seasoning
- Fresh basil: for that burst of herbal freshness always choose bright green leaves that look perky and fresh
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to four hundred degrees and let it heat while you prep the rest This ensures even cooking from the start
- Make the Oil and Vinegar Mixture:
- Whisk olive oil red wine vinegar minced garlic dried oregano and crushed red pepper flakes in a large mixing bowl Make sure everything is smoothly combined so the flavors coat every vegetable
- Toss the Vegetables:
- Add sliced bell peppers and onions into the bowl Toss them well so that every piece is slick and shiny from the oil mixture This step is what makes the veggies roast up tender and flavorful
- Layer in the Pan:
- Pour the vegetable mix into a nine by thirteen inch pan Spread evenly across the bottom Arrange the sausage pieces right on top so their juices drip into the veggies while roasting
- Bake to Perfection:
- Slide your pan into the oven and bake for forty to forty five minutes Check that the vegetables are tender and sweet and that the sausage is cooked through with a delicious golden color
- Finish and Serve:
- Scatter freshly sliced basil across the hot pan and either serve right from the dish or pile onto crusty rolls or pasta

My favorite part is the way roasted peppers turn almost buttery against the spiced sausage I will never forget my daughter getting excited for the first time about all those colorful veggies piled up next to her sausage because they looked like a rainbow on her plate
