Step‑by‑Step Instructions for Savory Sausage, Pepper, and Onion Quiche
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that when your Savory Sausage, Pepper, and Onion Quiche is ready to bake, it will cook evenly. Also, lightly spray a 9-inch pie plate with cooking spray to prevent sticking, or if you prefer, line it with your chosen pie crust, whether homemade or store-bought.
Step 2: Cook the Sausage
In a medium skillet, heat 1 tablespoon of avocado oil over medium-high heat. Once hot, crumble the 1 pound of breakfast sausage into the pan, cooking it until browned and cooked through, about 5-7 minutes. The sausage should be golden and fragrant. Remove the sausage from the skillet and set it aside, leaving the drippings behind for the next step.
Step 3: Caramelize the Onions
In the same skillet, add the diced yellow onion and reduce the heat to medium. Sauté the onion for 15-20 minutes until it becomes soft and caramelized, stirring occasionally. You’ll know it’s done when the onions are deep golden brown and smell sweet. This caramelization step adds essential flavor to your quiche.
Step 4: Sauté the Peppers and Garlic
Next, add the diced red and green bell peppers to the skillet with the caramelized onions. Cook them together for about 4-5 minutes until the peppers are tender. Then, stir in 2 cloves of minced garlic and cook for an additional 1-2 minutes, until the garlic is fragrant. This fragrant mixture will provide a delicious base for your quiche.
Step 5: Cool the Mixture
Once the vegetables are cooked, remove the skillet from heat and let the vegetable mixture cool slightly for about 5 minutes. This step is important to avoid cooking the eggs when mixed later. Ensure everything is well combined and let the rich flavors meld together while you prepare the next steps.
Step 6: Prepare the Custard
In a large mixing bowl, whisk together 4 large eggs, 1 cup of whole milk, and 1/3 cup of heavy cream until well blended. Add 1 teaspoon of dried sage, 1/2 teaspoon of kosher salt, and 1/2 teaspoon of black pepper to the mixture, blending everything until smooth. This custard will set the stage for the creamy filling of your Savory Sausage, Pepper, and Onion Quiche.
Step 7: Combine Ingredients
Gently fold the cooled sausage, sautéed vegetables, and 1 cup of shredded sharp cheddar cheese into the egg mixture. Ensure all ingredients are evenly coated with the custard, creating a flavorful blend. Take a moment to appreciate the vibrant colors and hearty textures that will soon become your delicious quiche.
Step 8: Assemble and Bake
Pour the entire filling mixture into the prepared pie crust, spreading it evenly. Carefully transfer the quiche to your preheated oven and bake for 45-55 minutes. Look for a golden top and a filling that is set but still slightly wobbly in the center—this is the perfect sign for a well-made Savory Sausage, Pepper, and Onion Quiche.
Step 9: Cool and Serve
Once baked, remove the quiche from the oven and allow it to rest for about 10 minutes before slicing. This resting time helps the quiche set up, making it easier to cut. Serve warm or at room temperature, and get ready to enjoy your wonderful homemade creation!

Expert Tips for Savory Sausage, Pepper, and Onion Quiche
- Pre-Cook Wisely: Always sauté your vegetables ahead of time. This prevents a soggy quiche by ensuring they’re fully cooked before baking.
- Blind Bake Trick: For a crispier crust, blind bake the pie crust for 10 minutes before adding the filling. This extra step is well worth it!
- Watch the Bake Time: Keep an eye on your quiche in the oven; it should be slightly jiggly in the center when done. Overbaking can lead to a rubbery texture.
- Let It Rest: Allow the quiche to rest for 10 minutes after baking. This helps the custard set properly and makes for cleaner slices.
- Customize the Cheese: Feel free to experiment with different cheeses in your Savory Sausage, Pepper, and Onion Quiche. Feta or mozzarella can add tasty twists!
How to Store and Freeze Savory Sausage, Pepper, and Onion Quiche
Fridge: Store your quiche in an airtight container in the refrigerator for up to 4 days. This keeps it fresh and ready for a quick meal!
Freezer: To freeze, wrap individual slices or the whole quiche tightly in plastic wrap and then in aluminum foil. It can last for up to 3 months without freezer burn.
Reheating: For best results, reheat slices in the microwave for 1-2 minutes. Alternatively, bake in the oven at 350°F (175°C) for 15-20 minutes to retain that delightful texture.
Serving Tip: When reheating, let it sit for a minute before slicing to allow the flavors to settle back in, making sure your Savory Sausage, Pepper, and Onion Quiche remains delicious!
Make Ahead Options
These Savory Sausage, Pepper, and Onion Quiche ingredients are perfect for meal prep lovers! You can cook the sausage, sauté the vegetables, and whisk the custard up to 24 hours in advance.
