Sausage and Peppers
Not rated yet. Be the first.
The peppers and onions hit the sausage fat and the whole kitchen starts to sizzle. Add browned tomato paste and a splash of vinegar at the end, and carry the skillet straight to the table.
The short version
Brown Italian sausages in a big skillet, cook sliced peppers and onions in the fat until soft and sweet, stir in garlic and tomato paste, then simmer the sausages back in until they reach 160°F. Finish with a splash of vinegar. About an hour.
What makes ours better
why ours wins the argument at dinner
-
Cook the vegetables in the sausage fat. The browned bits and rendered fat in the skillet are free flavor. Peppers and onions cooked in them taste like the sausage without any extra seasoning.
-
Brown the tomato paste. A couple of spoonfuls cooked for a minute until it darkens turn sweet and savory instead of raw and sharp. It also gives the vegetables a glossy red coating.
-
Finish with vinegar. A splash at the end cuts through the richness of the sausage and wakes up the sweetness of the peppers. Use balsamic, red wine vinegar or the brine from a jar of pickled cherry peppers.
-
Finish the sausage in the pan. Browning gives color but not a fully cooked sausage. A short covered simmer with the vegetables cooks it through without drying it out.

Brown the sausage
Heat the oil in a large, deep skillet or Dutch oven over medium heat. Add the sausages and cook, turning every few minutes, until deeply browned on all sides, about 10 minutes. They will not be cooked through yet. Move them to a plate and leave the fat in the pan.
Medium heat is enough. Higher heat can split the casings before the inside warms.
About 10 min. Cook mode has a timer for this step.
-
Soften the vegetables
Add the onions and peppers to the pan with the salt and pepper. Cook over medium heat, stirring every minute or two and scraping up the browned bits, until the vegetables are very soft and the onions are golden, about 20 minutes.
About 20 min. Cook mode has a timer for this step.
-
Add garlic and tomato paste
Push the vegetables to the sides, add the garlic, tomato paste and oregano to the middle, and cook, stirring, for 1 to 2 minutes, until the paste darkens to brick red. Stir everything together.
-
Simmer the sausage through
Pour in the water or wine and scrape the bottom of the pan. Nestle the sausages back in, cover, and simmer on medium-low until they reach 160°F in the center, 12 to 15 minutes. Turn them once halfway through.
Check the thickest sausage with an instant-read thermometer. Pale pink inside means keep going.
About 12 min. Cook mode has a timer for this step.
-
Finish with vinegar
Uncover, stir in the vinegar, and cook 2 minutes to thicken the juices into a glaze. Taste and add salt if needed.
-
Serve
Tuck a sausage into each toasted roll and pile on the peppers and onions, or serve over rice, polenta or pasta. Spoon on the pan juices.
Good to know
things I learned the hard way, so you can skip that part
- Sweet and hot sausage are interchangeable. Hot sausage plus a few pickled cherry peppers makes a spicier pan.
- Use fresh Italian pork sausage, not fully cooked links. Precooked sausage needs only the final simmer, so brown it for 5 minutes and shorten the simmer to 5.
- Slice everything the same thickness so the vegetables soften at the same rate. A mix of colors gives you sweeter peppers than all green.
- Storage. Refrigerate covered up to 4 days. Freeze sausages and vegetables together in their juices up to 3 months. Reheat gently in a skillet with a splash of water.
Questions, answered
asked and answered at the kitchen counter
How do I know when sausage and peppers is done?
The sausage reaches 160°F in the center, the peppers are completely soft, and the onions are golden. Cut into the thickest sausage if you don't have a thermometer. The meat should be uniformly cooked with no pink.
Can I bake sausage and peppers in the oven instead?
Yes. Roast the sausage, peppers and onions together on a sheet pan at 400°F for 35 to 45 minutes, turning once. You get less browning and less sauce, so toss with the vinegar at the end.
Should I boil the sausage first?
No. Boiling washes out flavor and gives you pale sausage. Brown it in the pan, then finish it with a covered simmer.
Can I make sausage and peppers ahead?
Yes, and it tastes even better the next day. Keep the sausage in the juices and reheat gently so the casings don't toughen.
What do I serve with sausage and peppers?
Hoagie rolls are classic. It's also good over creamy polenta with butter and parmesan, rice or buttered noodles, with a green salad on the side.
Which peppers are best?
Red, yellow and orange bell peppers are sweet and cook down soft. Add one green for a little bitterness. Italian frying peppers also work if you can find them.
