½ medium red onion, sliced
-
4 cloves garlic, minced

Instructions

Cook the Sausages:
In a large skillet, cook the sweet Italian sausages over medium heat. Brown the sausages for about 8-10 minutes, turning occasionally, until they are cooked through and golden brown. Remove the sausages from the skillet and set them aside. Once slightly cooled, slice the sausages into 1-inch pieces. -
Sauté the Vegetables:
In the same skillet, melt the butter over medium heat. Add the sliced yellow and red onions, and cook for 3-4 minutes until they begin to soften. Add the minced garlic, red bell pepper, and green bell pepper to the skillet. Sauté for an additional 5-7 minutes until the peppers and onions are tender and slightly caramelized. -
Season the Mixture:
Stir in the dried basil and oregano, and season with salt and pepper to taste. Mix well. -
Deglaze with Wine:
Pour in the white wine, scraping the bottom of the skillet to loosen any browned bits. Let the wine simmer and cook off for 2-3 minutes, allowing the flavors to meld together. -
Combine the Sausage:
Return the sliced sausage to the skillet and stir to combine with the peppers and onions. Continue to cook for an additional 3-5 minutes to ensure everything is heated through and the flavors are well-combined. -
Serve:
Serve the Italian sausage, peppers, and onions hot, either on a platter or with your choice of side dishes such as pasta, bread, or a salad.
Notes
For extra flavor, add a sprinkle of red pepper flakes for some heat.
If you prefer a less oily dish, you can use leaner sausage or remove some of the rendered fat before adding the wine.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet or microwave.

Keywords: Italian Sausage, Peppers, and Onions
Instructions:
- Cook the Sausages: Begin by heating a large skillet over medium-high heat. Add the Italian sausages to the skillet and brown them on all sides. This should take about 5-7 minutes. Once browned, remove the sausages from the skillet and set them aside on a plate.
- Sauté the Vegetables: In the same skillet, reduce the heat to medium and add the butter. Let it melt, then add the yellow onion, red onion, and garlic. Cook, stirring occasionally, for 3-4 minutes until the onions become soft and fragrant.
- Add the Bell Peppers: Once the onions have softened, add the red and green bell peppers to the skillet. Stir in the basil and oregano, and continue cooking for an additional 4-5 minutes, or until the peppers begin to soften.
- Deglaze the Pan: Pour in the white wine to deglaze the pan, scraping up any browned bits from the bottom of the skillet. This will add extra flavor to the dish. Allow the wine to simmer for 2-3 minutes, letting it reduce slightly.
- Return the Sausages to the Skillet: Place the browned sausages back into the skillet with the vegetables. Cover the skillet and simmer for an additional 10-12 minutes, turning the sausages occasionally, until they are fully cooked through (internal temperature should reach 160°F).
- Serve and Enjoy: Once the sausages are cooked through and the vegetables are tender, remove from heat. Slice the sausages into bite-sized pieces, if desired, and serve the dish on its own or with your favorite side.
Advanced Techniques
While the basic recipe for Italian Sausage, Peppers, and Onions is straightforward, there are several advanced techniques you can use to elevate this dish and add depth to the flavors.
Grilling the Sausages
Instead of cooking the sausages in a skillet, grill them for added smoky flavor. Preheat your grill to medium-high heat and cook the sausages for 8-10 minutes, turning occasionally, until fully cooked. This adds a delicious char to the sausages that complements the sweetness of the peppers and onions.
Caramelizing the Onions
For an extra layer of sweetness and richness, take the time to caramelize the onions. After adding the onions to the skillet, reduce the heat to medium-low and let them cook for 15-20 minutes, stirring occasionally. The slow cooking process will bring out their natural sugars and create a more intense flavor profile.
Adding Red Wine
For a deeper, more complex flavor, swap out the white wine for red wine. This will provide a bolder, slightly tannic backdrop to the dish, complementing the richness of the sausage and the sweetness of the peppers and onions. If you choose this option, let the wine simmer for a few extra minutes to allow it to reduce and concentrate.
Making it Spicy
If you enjoy heat, add a pinch of red pepper flakes to the dish or use spicy Italian sausage instead of the sweet version. This will give the dish an extra kick and balance the sweetness of the peppers and onions.
