Healthy Breakfast Recipes with Sourdough

Starting your day off with a high-protein breakfast can help keep your blood sugar stable, prevent energy crashes, help you stay full for longer and help repair and build muscle. I love starting out the morning with a satisfying and healthy breakfast. From sourdough protein pancakes, sourdough protein muffins with fresh berries, to a sourdough egg bake, I have several delicious, easy meal prep options to start your day off right. 

Selecting a protein powder

Not all protein powders are the same and the type of protein powder you use can impact the flavor and texture of these waffles. My favorite protein powder is from Just Ingredients (use my link for 10% off). Some of my favorite flavors from them include vanilla bean and chocolate coconut. I love this brand of protein powder because it has simple, clean ingredients. There is no added sugar or sugar alcohol, and it is sweetened with stevia and monk fruit. One scoop of powder has 22 grams of protein from grass-fed non-denatured whey, pea protein, chia seed protein, and grass-fed collagen!

Ingredients

• Sourdough discard – Adds moisture and tanginess to the waffles. If you don’t currently have a sourdough starter check out my recipe to make one in just 2 weeks.
• Plain greek yogurt – The greek yogurt adds moisture and additional protein. I had non-fat on hand so that is what I used in the recipe, but using one with fat will add more moisture. You could swap out plain for vanilla or another flavor, if preferred. 
• Eggs – To bind the waffles (plus adds more protein!)
• Milk – You can use any type but using one with more fat, like whole milk, will make the waffle more moist.
• Protein powder – I use Just Ingredients Protein Powder.
• Baking powder & baking soda – Both of these ingredients help give the waffles a fluffy rise.
• Salt – Any type will work.
• Flour – Ideally use unbleached all-purpose flour. I use Sunrise Flour Mill All-Purpose Flour in this recipe.

Sourdough Protein Waffle mix-ins

You can really customize this recipe to include your favorite flavors and mix-ins. For a fall inspired waffle, try using Apple Cider Protein Powder, 1 cup of apples and a teaspoon of cinnamon in your batter. Or for a light, citrus flavor, try Vanilla Protein Powder, 1 cup of blueberries and zest of one lemon. Or if you are a chocolate lover try Chocolate Coconut Protein Powder and some chocolate shavings. The possibilities are endless, so have fun with it. Try adding different fruits such as bananas, raspberries, or blackberries or go sweet with chocolate chips and nuts.

Instructions

Preheat: Plug in the waffle maker and start preheating it while mixing the batter.

Mix the wet ingredients: In a bowl, I like to use a batter bowl with a spout, whisk together the sourdough discard, eggs, milk, and greek yogurt.

Add in the dry ingredients: To the bowl add the protein powder, baking powder, salt, baking soda, and all-purpose flour. You can mix these in a separate bowl before adding the mixture, if preferred, but I find it easier to just add them directly. Mix the batter until just combined, don’t overmix. The consistency of the batter should be thick. A thicker batter will ensure it does not run off the waffle iron when making these. 

Bake: Spray the waffle maker with non-stick cooking spray. Pour batter onto the waffle maker. This recipe makes 4 waffles so pour about one fourth of the batter at a time, baking in batches. All waffle irons are slightly different, so follow the instructions on yours to bake. 

Serve and enjoy! 

Can Sourdough Protein Waffles be made ahead of time?

Yes! These waffles will last in the fridge for about a week if stored in an airtight container. Before placing in the refrigerator, ensure the waffles are completely cooled. These are a great option to make ahead of time for breakfast throughout the week, just pop in the toaster oven or microwave to heat up and enjoy.

Alternatively, you can also freeze the Sourdough Protein Waffles so you always have a quick, high-protein breakfast on hand! Be sure the waffles are completely cooled first. To freeze, add the waffles to a sheet pan in a single layer and place them in the freezer for an hour. Then take the frozen waffles and add them to a freezer bag for storage. Alternatively, add the waffles directly to a freezer bag with parchment paper in between each to ensure they don’t stick together.
