Sourdough Bacon And Cheddar Breakfast Muffin Ingredients
For the Muffin Batter
• Sourdough Starter Discard – Provides a tangy flavor and helps create a fluffy texture; substitute with 1 cup of buttermilk for a different taste.
• All-Purpose Flour – Gives structure to the muffins; whole wheat flour can be used for a healthier alternative but may change the texture slightly.
• Sharp Cheddar Cheese – Adds a robust flavor; feel free to swap with Monterey Jack or pepper jack for a spicy kick.
• Crispy Bacon – Infuses rich, savory goodness; substitute with turkey bacon or cooked sausage for a lighter option.
• Green Onions/Chives – Introduces a fresh, vibrant note; can be omitted or replaced with finely chopped garlic for a different flavor profile.
• Baking Powder – Essential for leavening and giving those muffins a beautiful rise.
• Baking Soda – Works with sourdough to help achieve that perfect fluffy texture.
• Salt – Enhances the overall flavor; don’t skip it!
For Storage
• Airtight Container – Store muffins at room temperature for 2 days, or in the fridge for up to a week; freezing also keeps them fresh for 3 months.
This delightful combination of ingredients will bring your bacon and cheddar breakfast muffins to life, ensuring a warm hug for your taste buds!
Step‑by‑Step Instructions for Sourdough Discard Bacon and Cheddar Breakfast Muffins
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). Prepare a 12-cup muffin tin by greasing it lightly or placing paper liners in each cup. This ensures that your Sourdough Discard Bacon and Cheddar Breakfast Muffins will release easily after baking, giving you perfectly shaped muffins every time.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine 1 cup of sourdough starter discard, 2 cups of all-purpose flour, 1 tablespoon of baking powder, 1/2 teaspoon of baking soda, and 1/2 teaspoon of salt. Use a whisk to blend these dry ingredients until they are evenly distributed. This step is essential for achieving a uniform texture in your bacon and cheddar breakfast muffins.
Step 3: Combine Wet Ingredients
In another medium bowl, beat together 2 large eggs until fluffy. Then, add in 1 cup of milk and 1/4 cup of melted butter, whisking until thoroughly mixed. This mixture will bring moisture and richness to the muffins, complementing the savory flavors of the bacon and cheddar.
Step 4: Combine Wet and Dry Mixtures
Gently pour the wet mixture into the bowl with the dry ingredients, stirring with a spatula until just combined. It’s okay if the batter has a few lumps—avoid overmixing to prevent dense muffins. This critical step ensures your Sourdough Discard Bacon and Cheddar Breakfast Muffins remain fluffy and light.
Step 5: Fold in Additions
Carefully fold in 1 cup of sharp cheddar cheese, 1/2 cup of crispy bacon (cooked and crumbled), and 1/4 cup of finely chopped green onions. This will enhance the flavor and texture, ensuring every bite of your breakfast muffins is filled with delightful savory goodness.
Step 6: Fill Muffin Tin
Using a spoon or an ice cream scoop, fill each muffin cup with the batter until it is nearly full, leaving a little space for rising. Aim for a consistent fill across all cups to ensure even baking. Your Sourdough Discard Bacon and Cheddar Breakfast Muffins are now ready for the oven!
Step 7: Bake Muffins
Place the muffin tin in the preheated oven and bake for 18 to 22 minutes. The tops should turn golden brown and a toothpick inserted into the center should come out clean. This signals that the muffins are cooked through and ready to bring a delicious aroma into your kitchen.
Step 8: Cool and Serve
Once baked, remove the muffin tin from the oven and allow the muffins to cool in the tin for about 5 minutes. After they’ve slightly cooled, gently transfer them onto a wire rack. This cooling period enhances the texture and flavor of your Sourdough Discard Bacon and Cheddar Breakfast Muffins, making them even more enjoyable to eat.

Storage Tips for Bacon and Cheddar Breakfast Muffins
Room Temperature: Store muffins in an airtight container at room temperature for up to 2 days to maintain their delightful fluffiness.
Fridge: Refrigerate in an airtight container for up to 1 week; this helps preserve flavor but may slightly alter texture.
Freezer: Freeze for up to 3 months in a freezer-safe container. When ready to enjoy, thaw completely before reheating for best results.
Reheating: Warm in a preheated oven at 350°F (175°C) for about 10 minutes, or microwave for 20-30 seconds, ensuring they’re perfectly cozy and ready to savor!
Make Ahead Options
These Sourdough Discard Bacon and Cheddar Breakfast Muffins are perfect for meal prep enthusiasts! You can mix the dry ingredients and the wet ingredients separately, refrigerating them for up to 24 hours to save time on busy mornings. When you’re ready to bake, simply combine the two mixtures along with the cheese and bacon, and follow the baking instructions. For even greater convenience, you can also prepare the muffins in full and freeze them for up to 3 months. Just let them cool completely, then wrap them tightly in plastic wrap and store in an airtight container. To enjoy them later, reheat gently in the oven or microwave for delicious, ready-to-eat muffins that are just as tasty as fresh-baked!

Sourdough Discard Bacon and Cheddar Breakfast Muffins Recipe FAQs
What type of sourdough starter should I use?
Absolutely, you can use any sourdough starter discard, whether it’s firm or liquid. Just make sure it’s been fed recently for the best flavor. If you’re new to sourdough, a well-matured starter with bubbles and a pleasant tang will give you the best results.
How should I store my muffins?
I recommend storing your muffins in an airtight container at room temperature for up to 2 days, ensuring they stay fluffy and fresh. For longer storage, you can refrigerate them for up to a week. If you want to hold onto them for even longer, freeze the muffins in a freezer-safe container for up to 3 months. Just remember to let them cool completely before freezing to maintain texture!
Can I freeze these breakfast muffins?
Yes, you can absolutely freeze your Sourdough Discard Bacon and Cheddar Breakfast Muffins! To do this, wrap each muffin individually in plastic wrap and then place them in a freezer-safe container. When ready to enjoy, thaw them completely in the fridge overnight, and reheat in the oven at 350°F (175°C) for about 10 minutes for that fresh-baked taste.
What if my muffins turn out dense?
Very good question! If your muffins are dense, it’s often due to overmixing the batter or using too much flour. When combining the wet and dry ingredients, stir gently until just combined—lumps are totally fine! Also, ensure you’re measuring flour correctly by spooning it into your cup and leveling it off without packing.
Are there any dietary considerations?
Yes! These muffins can be adapted to suit various dietary needs. For a gluten-free option, use a 1:1 gluten-free flour blend, making sure all other ingredients are gluten-free as well. You can also swap the bacon with turkey bacon or even sautéed vegetables for a vegetarian version. Just be mindful if anyone has allergies—always check that your cheese and other ingredients fit their dietary restrictions!
