Italian Sausage and Peppers FAQs

Can you put raw sausages in a slow cooker?

Yes! Cooking the sausage raw in the crockpot with the veggies, seasonings, and sauce will produce a tasty, juicy, and tender piece of sausage that is cooked to perfection.

Can I use frozen sausages in the slow cooker?

Yes! From the freezer, add everything to the slow cooker—cook on high for 1 1/2 hours and then on low for 6 hours.

How do you make sausage and peppers less greasy?

There are a few ways to make sausage and peppers less greasy. Here are a few tips:
Use lean sausage. Many different types of sausage are available, and some are leaner than others. Choose a sausage low in fat and calories, such as turkey or chicken sausage.
Drain the sausage. After browning the sausage, drain off any excess grease. This will help to reduce the amount of fat in the final dish.
Cook the peppers in a separate pan. This will help to prevent the peppers from absorbing as much grease from the sausage.
Add a splash of water or broth to the pan. This will help to deglaze the pan and prevent the sausage from sticking.
Cook the sausage and peppers over medium heat. This will help to prevent the sausage from rendering too much fat.

How do you know when sausage is cooked in a crock pot?

To know when sausage is cooked in a crock pot, you can check it by:
Using a meat thermometer: Insert a meat thermometer into the thickest part of the sausage. The internal temperature should be 165 degrees Fahrenheit.
Tasting it: Sausage is cooked when it is no longer pink and has a firm texture. You can also taste a small piece to ensure it is cooked.
Cutting into it: If you cut into the sausage and it is no longer pink, and the juices run clear, it is cooked through.

Do you cook sausages on high or low?

Sausages can be cooked on low heat in a crock pot for 4-6 hours or on high heat for 2-3 hours. The cooking time will vary depending on the type and thickness of the sausage.

  1. I’ve added chicken thighs and they were delicious-along with the sausage.

  2. Can you make this with brats?

    1. I haven’t tried this recipe with brats, but I bet you can. If you try it, let me know how it turns out!

    2. Colleen B. says:

      I have used Brats but I did lightly brown them on all sides first in cast iron skillet and used one whole pepper of t red, yellow, orange and green bell peppers; thinly sliced.

  3. It was fantastic. The sauce was rich and tasty.
    Made it for a football game.

  4. Absolutely delicious and easy! Just made this for dinner tonight. I used Merlot instead of the Marsala. The only thing I would do differently would be to triple the peppers. I will definitely be making this again. Thank you

  5. Absolutely love this. Used the chicken broth not wine and skipped the fennel because hubby doesn’t like it. The texture of the sausage was perfect and the sauce divine. The sauce thickened nicely upon removing it from heat. I used only sweet Italian sausage but the red pepper flakes added just the right amount of hot.

  6. Did u brown the sausage first ?

    1. Food Folks and Fun says:

      I did not brown the sausage first but you can! Please tell us how it turns out.

  7. I have made this several times and thought I should review it. Wonderful simple recipe with quality ingredients. I was in a rush today so I cooked it in my Dutch oven at 325 for 2 hours and 30 minutes. Came out beautiful! Thank you so much!!
