Slow Cooker Breakfast Sausage and Pepper Sandwich

Steps

1. 1

   Brown the sausage links

   • Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
   • Place the sausage links in the skillet and brown on all sides, about 7–10 minutes total, turning occasionally.
   • The goal is to develop a golden-brown crust; they don't need to be cooked through at this point.
   • Transfer browned sausages to a paper towel-lined plate to cool slightly.

   Ready when: Sausage links are golden-brown on all sides

   Tip: Browning creates a flavorful crust through caramelization, adding depth to the final dish. Don't skip this step even though the sausages will finish cooking in the slow cooker.

2. 2

   Prepare vegetables

   • While the sausage cools, cut the red bell peppers in half lengthwise, remove seeds and stems, then slice into 1/2-inch strips.
   • Slice the yellow onions into 1/2-inch rings, separating the rings as you go.
   • Mince the garlic cloves.
   • This prep takes about 8–10 minutes.
   • You can start this step while the sausage is browning to save time.

   Ready when: All vegetables are chopped to size and ready to use

   Tip: Uniform vegetable sizes ensure even cooking in the slow cooker.

3. 3

   Transfer to slow cooker

   • Add the browned sausage links, sliced peppers, onion rings, and minced garlic to a 4–6 quart slow cooker.
   • Sprinkle over 1.5 teaspoons Italian seasoning, 0.5 teaspoon kosher salt, 0.25 teaspoon black pepper, and 0.5 teaspoon red pepper flakes (if using).
   • Stir gently with a wooden spoon to distribute seasonings and vegetables around the sausages.
   • Cover with the lid.

4. 4

   Slow cook on LOWOven 160°F / 70°C

   • Cover the slow cooker and cook on LOW for 6–8 hours.
   • The sausage should reach an internal temperature of 160°F (71°C) and be cooked through, while the peppers and onions will become very soft with caramelized, slightly browned edges.
   • If you're short on time, use the HIGH setting for 3–4 hours instead, though the LOW setting produces better flavor and caramelization.
   • You can stir once halfway through if convenient, though it's not necessary.

   Ready when: Sausage reaches 160°F internal temperature, peppers and onions are very soft with browned edges

   Tip: For shorter cooking, use HIGH for 3–4 hours, but LOW gives you better caramelization and deeper flavor.

5. 5

   Toast rolls and assembleOven 375°F / 190°C

   • About 10–15 minutes before serving, preheat your oven to 375°F (190°C).
   • Split the sandwich rolls horizontally.
   • Lightly brush the inside of each roll with butter if desired.
   • Place rolls cut-side up on a baking sheet and toast in the preheated 375°F (190°C) oven for 3–4 minutes, until the insides are warm and just beginning to turn golden.
   • (Alternatively, use a toaster oven or regular toaster.) Once toasted, use a slotted spoon or tongs to lift one sausage link and a generous handful of peppers and onions (about 1/2 cup per sandwich) from the slow cooker and place in each roll.
   • Top each sandwich with 1–2 slices of provolone cheese.
   • Serve immediately.

   Ready when: Rolls are warm and lightly toasted on the inside, cheese is just melting

   Tip: Toast rolls just before serving to maintain the best texture. If they sit too long after toasting, they'll firm up.
