One of our favorite meals, especially when it is cold, is a big dish of Italian sausages and peppers.  Normally, I cook everything on top of the stove in a frying pan, but for this recipe, I decided to finish this one pot meal in the oven to give it more of a roasted flavor.

Making these oven baked Italian sausage and peppers.

I used yellow and red peppers to make this but I have done it with green, as well. Any peppers will do, though and you can add in other veggies as well.

Today, it was onions, garlic, mushrooms and sliced celery with the peppers.

Start by browning the sausages in an oven proof saute pan on the stove over a medium high heat. You just want to get a bit of color to them and partially cook them to save on the oven time, but not cook them all the way through.

Remove and set them aside.Browining sausages in a saute pan.

Put the onions, celery and pepper in the same pan and cook for a minute or two, to give them a nice char.  Once again. Don’t cook them until they are soft. Just stir them around until they get a bit of browning going on.

I didn’t use any oil in the recipe, but did have a bottle of coconut oil spray that I used during each addition, just to keep the vegetables from sticking.Onions, celery and sweet peppers

Stir in the mushrooms and garlic, cook for another minute.  Look at that color and all those fresh flavors!Add the mushrooms and garlic

Stir in the diced tomatoes, basil, Italian seasonings, and salt and pepper.  Give everything a really good stir and then lay the sausages over the top of the vegetables.Sausages over vegetables

Place the whole pan in a preheated 375 º oven for about 20-25 minutes until the sausages are cooked through and the vegetables are nicely roasted.  Easy peasy!Sausage and peppers in the oven

Tasting this baked Italian Sausage and Peppers Recipe

The dish ended up beautifully done.  Baking it in the oven left the vegetables with a still crispy texture and roasted vegetable taste that we really loved.  (they end up much softer when cooked on the stove top.)

And the sausages cook and flavor the vegetables below so that the whole dish has one great taste that only comes from one pot cooking.

Each layer of flavor adds a bit more taste to the dish until it all comes together in such a wonderful way.Serving these one pot Italian sausages

The taste of this dish is both savory from the tomato sauce and seasonings, and spicy from the flavor of the Italian sausages, but without too much heat.  It’s warm and comforting and perfect for a busy winter night.Tasting Italian sausages and peppers

We have this dish often. Sometimes I serve it on its own and other times I switch it up to use green peppers and add some cooked pasta. Whichever way we have it, it’s always a favorite!
