Packed with protein, they will keep you full and energized throughout the day. Whether you’re a fitness enthusiast or just looking for a tasty breakfast option, sourdough protein waffles are sure to be a hit.

What are sourdough protein waffles?

Sourdough Protein Waffles are a nutritious and delicious breakfast option that combines the tangy flavor of sourdough with the protein-packed goodness of waffles. 

Made with a blend of whole grain flour, eggs, milk, and sourdough starter, these waffles are not only delicious but also provide a great source of protein to start your day off right. They can be topped with fresh fruit, nut butter, or syrup for an extra boost of flavor. The good news is that these healthy protein waffles are so good and this is an easy way to feed your family for cheap.

Ingredients Needed for Sourdough Protein Waffles

  • Sourdough discard which means it is starter that is flat and runny. It can be used in recipes to add tangy flavor and a slight chewiness to baked goods. You’ll need one cup to make this batter. I discuss sourdough discard more in this post!
  • Eggs are a staple ingredient in many baking recipes. They provide structure, moisture, and richness to baked goods. In this case, they are going to add protein, too! One egg has approximately 6 grams of protein. I also love eggs because they provide you with the 9 essential amino acids, healthy fat, nutrients like vitamins A, D and E, choline and folate.
  • Protein powder is a supplement often used by athletes or people looking to increase their protein intake. It is typically made from whey, casein, soy, or pea protein and can be added to smoothies or baked goods for an extra boost of protein. Did you know starting the day with protein helps with metabolism, mood, concentration and energy?
  • Oil is used in baking recipes to add moisture and richness. Avocado oil and coconut oil are both healthy options that add unique flavors to baked goods. Melted butter is also commonly used in baking recipes for its rich flavor.
  • Milk is used as needed to thin batter, this depends on how thick/thin your starter is: Milk is another ingredient that adds moisture to baked goods. You can use dairy milk or non-dairy milk such as almond milk, or oat milk depending on your preferences. The amount you use will depend on the thickness of your batter.
  • Chia seeds are a popular superfood that is high in fiber and omega-3 fatty acids. They can be added to baked goods for extra texture and nutrition.

How to Store Sourdough Protein Waffles

To store sourdough protein waffles, allow them to cool completely first. Once cooled, you can store them in an airtight container in the refrigerator for up to 5 days. 

If you prefer to freeze them for longer storage, wrap each waffle individually or layer them with parchment paper and place them in a freezer-safe bag. 

They will keep well in the freezer for up to 2 months. When you’re ready to enjoy your waffles, simply reheat them in a toaster or oven until they are warmed through and crispy on the outside.

Do waffles normally have protein?

If the recipe calls for eggs, yes, waffles can have protein. We’re doubling up on protein here with the addition of more eggs than typical and by adding protein powder. Topping with a dollop of Greek yogurt on top will give you even more! If you use Just Ingredients protein powder these waffles contain about 18 grams of protein each!

A note on protein powder

I hate to say it but there are a lot of awful protein powders on the market. These aren’t something I typically eat myself, let alone feed my kids! The problem with most protein powders on the market:

They contain artificial flavors, dyes and/or sweeteners. The are a HUGE problem in the body. These ingredients are inexpensive and contain chemicals that don’t have to labeled. They can contribute to ADHD symptoms, asthma, type II diabetes, weight gain and IBS

They use gums, thickeners and emulsifiers. These are in most processed foods! The problem is that they can be a gut irritant and potentially trigger inflammation.

-Many are 100% conventional whey which can be why it causes to many people digestive issues. Another possibility is 100% pea protein and that can also cause digestive stress.

What protein powder I like best

It can be tough to find a protein powder that actually contains whole food ingredients without any artificial ingredients, fillers, gums or flow agents. I love Just Ingredients protein powder because it is full of nourishing whole foods like collagen, pumpkin seeds, chia seeds and pea protein.

Another great fact about this protein powder is that it has 100% non-denatured whey protein. This means that it is easier on your digestive system while also being better absorbed by the body. Just Ingredients protein powder also contains about 5 grams of each type of protein rather than being from all one source.

Our favorite flavors to use in these protein waffles is vanilla and snickerdoodle. It makes for the most delicious waffles! Find Just Ingredients protein powder here. Don’t forget to use code LAURAT10 for a discount!

Topping Options for Sourdough Protein Waffles

This is the fun part! Here are some delicious toppings and additions you can enjoy with protein waffles:

  • Fresh berries (such as strawberries, blueberries, or raspberries)
  • Greek yogurt
  • Nut butter (such as almond butter or peanut butter)
  • Honey or maple syrup
  • Chocolate chips or a drizzle of chocolate sauce
  • Sliced bananas
  • Chopped nuts (such as almonds, walnuts, or pecans)
  • Chia seeds, ground flaxseeds or hemp hearts
  • Whipped cream (made with raw cream is our favorite!)

The possibilities are endless when it comes to topping your protein waffles. Get creative and experiment with different combinations to find your favorite!

      I’m so happy you’re loving these waffles! They hold up well for 2-3 days in the refrigerator and freeze for 3-6 months. I put a piece of parchment paper in between them so they are easy to get out and re-heat 🙂

  2. I don’t have sourdough starter (or discard), can I substitute with kamut flour instead? Have you tried this recipe with flour? I’m really looking for a truly high protein waffle/pancake for my kids and this one looks yummy. Thank you!
