Creamy High-Protein Oatmeal Recipe

Egg whites can add protein to oatmeal without changing the flavor, but they must be streamed into simmering oats while whisking. Greek yogurt goes in off the heat so it stays creamy instead of separating.

The ingredient amounts and timing are sized for 2 bowls. Ingredient brands, starting temperature, piece size and natural moisture can change the finish, so use the texture and doneness cues below along with the clock.

Why this recipe works

Egg whites are streamed slowly: Whisking prevents visible scrambled curds.

Yogurt is off heat: Gentle addition protects a smooth creamy texture.

Milk and water: The combination gives body without making the finished oats overly rich.

Ingredients

• 1 cup old-fashioned rolled oats
• 1 1/2 cups milk
• 1/2 cup water
• 1/2 cup liquid egg whites
• 1/2 cup plain Greek yogurt
• 1 tablespoon maple syrup
• 1/2 teaspoon cinnamon
• 1/4 teaspoon salt
• 1 cup berries, for serving

Ingredient notes

Oats: Old-fashioned oats stay creamy with visible texture.

Egg whites: Use pasteurized carton whites for easy measuring.

Greek yogurt: Plain 2% or full-fat folds in most smoothly.

How to make high protein oatmeal

1. Simmer oats

Bring milk, water and salt to a gentle simmer; stir in oats and cinnamon.

2. Cook

Cook 5 minutes, stirring until the oats begin to thicken.

3. Add egg whites

Lower heat and slowly stream in egg whites while whisking constantly.

4. Finish cooking

Cook 2 to 3 minutes until creamy and no liquid egg remains.

5. Add yogurt

Remove from heat, stand 1 minute, then fold in Greek yogurt and maple syrup.

6. Serve

Divide into bowls and add berries.

Substitutions and variations

No egg

Omit egg whites and stir in cottage cheese blended smooth after cooking.

Dairy-free

Use soy milk and a thick plant yogurt; protein will differ.

Chocolate

Whisk in 1 tablespoon cocoa with the oats and add banana at serving.

Serving ideas

Add berries, chopped nuts or peanut butter. Keep crunchy toppings separate for meal prep.

For an oat breakfast you can bake into portions, cottage cheese and banana protein muffins uses a blended oat batter without protein powder.

Troubleshooting

Problem	Likely cause	What to do
Egg curds appear	Whites were added quickly without whisking.	Blend briefly or whisk vigorously off heat; stream more slowly next time.
Oats are too thick	They stood too long.	Stir in warm milk a tablespoon at a time.
Yogurt separates	It was boiled.	Remove from heat before folding it in.
Flavor is flat	It needs salt or fruit acidity.	Add a pinch of salt and fresh berries before more sweetener.

Storage, freezing and reheating

Refrigerator: Refrigerate up to 4 days.

Freezer: Freeze portions up to 2 months, though texture softens.

Reheating: Warm with a splash of milk, stirring often.

For general handling, the USDA food thermometer guidance is the outside reference used for this article. USDA lists 160°F for eggs and 165°F for casseroles and poultry; use a thermometer when safety certainty matters.

Frequently asked questions

Does it taste like eggs?

Not when the whites are streamed and fully incorporated.

Can I use quick oats?

Yes, with less cooking time and slightly less liquid.

Can I make it overnight?

Cook ahead and reheat; this is not a no-cook overnight-oats formula.
