Tips for making baked sausage and peppers with sauce

  • I prefer to cut my sausage links into thirds to make them more appropriate for an appetizer (and easier to eat). You can always keep them whole if serving as an entree, just be sure you temp them before serving to make sure they cooked through, as smaller ones tend to cook a bit faster (the cook time may vary).
  • I like to whisk all the sauce ingredients together in a large bowl and then stir in the vegetables.
  • Be sure to spray your baking pan down with olive oil cooking spray and arrange the sausage pieces along the bottom of the pan. Pour the sauce evenly over the sausages.
  • You’ll bake this uncovered so that the sauce thickens slightly as it cooks.

What kind of sausage can I use?

I always go with Italian sausage (turkey or chicken Italian sausage will make it a bit more heart healthy). My personal preference is spicy but if you aren’t into spicy foods then use sweet Italian sausage.

Which color bell peppers are best to use?

You can use any color you’d like- I prefer green or red peppers.

Can I use other veggies?

You can totally substitute other veggies for the same amount of peppers!

What if I don’t cook with alcohol?

No problem, you can always substitute with the same amount of chicken broth.

What goes good with Italian sausage?

I like to serve this as an appetizer with tooth picks and some crusty bread to sop up all the delicious sauce. You can also serve it over pasta or spaghetti squash for a satisfying dinner.

Can I make this baked Italian sausage ahead?

Yes, you can assemble it all ahead and bake it just before serving. You can also make it and transfer it to a slow cooker set to warm to keep it warm and delicious for the party.

How long do baked sausage, peppers and onions last?

Around 3-4 days covered in the refrigerator.
