Sourdough starter breakfast bites are an easy, flavorful way to start the day. These savory bites combine eggs, peppers, mushrooms, spinach and active sourdough starter to create a tender, textured base that holds plenty of fresh produce. They come together quickly, bake in a muffin tin, and freeze beautifully for fast breakfasts throughout the week.
The idea for these bites comes from classic egg bites, but adding sourdough starter gives them more body and a pleasant subtle tang. The starter helps improve volume and texture so the bites are less dense and hold the chopped vegetables nicely. If you already maintain a sourdough starter, this recipe is a smart way to use some of it while adding variety to your morning routine.
If you don’t have a fully active starter, you can still use sourdough discard—just add a teaspoon of baking soda to the batter to help them rise. The recipe is flexible: add your favorite vegetables, swap cheeses, or add spices to suit your taste.
Ideas for other breakfast uses of your sourdough discard include pancakes, waffles, scones and biscotti. These bites are another simple, savory option that pairs well with hot sauce or a smear of your favorite condiment.
Ingredients
Sourdough starter: For best results use an active, bubbly sourdough starter that has been fed and is at peak (typically 6–12 hours after feeding). If using discard or a less active starter, add 1 teaspoon baking soda to the batter to aid rise.
Fresh produce: I typically use red bell pepper, baby bella mushrooms, and baby spinach, all finely chopped. This recipe is very adaptable—try shredded carrot, zucchini (squeeze out excess liquid), chopped broccoli, or green onion.
Other ingredients: Eggs, a small amount of milk for richness, herbs and seasonings (parsley, oregano, onion powder, garlic powder, salt), and shredded cheddar cheese for topping.
How to Make
This recipe is straightforward and quick. Mix the components, spoon into a muffin tin, bake, and you’ll have a healthy, portable breakfast in about 40 minutes total.
1. Preheat the oven to 350°F (175°C) and prepare a 12-cup muffin pan (non-stick or sprayed with cooking oil).
2. In a large bowl, combine the sourdough starter with the chopped produce and seasonings. In a separate bowl, whisk together the eggs and milk, then fold the egg mixture into the starter-vegetable mix until evenly combined.
3. Divide the batter between 12 muffin cups, filling each about 3/4 full. Top each with a sprinkle of grated cheddar.
4. Bake at 350°F for 30–35 minutes, until the centers are set, the edges are golden, and the cheese has melted.
Let the bites cool in the pan for about 5 minutes, then remove and serve warm. They’re delicious with hot sauce, ketchup, or a spicy fermented paste like gochujang. They also travel well for grab-and-go breakfasts.
These bites are a simple way to get protein and vegetables into your morning. They’re forgiving—adjust seasonings and mix-ins to your liking, and keep a few in the freezer for busy mornings.
Storage
Store cooled breakfast bites in an airtight container in the refrigerator for up to a few days.
To freeze, place fully cooled bites in a freezer-safe bag or container. Thaw overnight in the refrigerator, then microwave 20–30 seconds or warm in an oven or toaster oven until heated through.
Equipment
A 12-cup muffin pan is the easiest way to make these. A batter bowl or measuring pitcher with a pour spout is helpful for transferring the mixture into the muffin tin cleanly, but you can use a spoon if needed.
