Egg Whites and Other Essentials

• 2 cups rolled oats (quick or old-fashioned are both great)
• 1 cup egg whites
• ¼ cup chia seeds (or flaxseeds)
• ¼ cup hemp seeds (hulled hemp hearts)
• 1.5 cups pure pumpkin puree (not pumpkin pie filling)
• 1 cup milk (any kind you like)
• ¼ cup coconut sugar (or brown sugar)
• 1 teaspoon vanilla extract
• 1 teaspoon cinnamon
• ¼ cup chocolate chips (optional — feel free to add nuts too!)
• ½ teaspoon salt
• 1.5 cups Greek yogurt (plain, non-fat, mixed into the oats)
• 1.5 cups Greek yogurt (plain, non-fat, perfect for topping when serving)

One-Bowl Baking Instructions

1. Preheat oven to 350°F and grease a 9×13-inch baking dish.
2. In the prepared baking dish combine 2 cups rolled oats, 1 cup egg whites, 1.5 cups Greek yogurt, 1/4 cup chia seeds, 1/4 cup hemp seeds, 1.5 cups pumpkin puree, 1 cup milk, 1/4 cup coconut sugar, 1 teaspoon vanilla extract, 1 teaspoon cinnamon, and 1/2 teaspoon salt; mix until well combined.
3. Sprinkle 1/4 cup chocolate chips on top and gently press them into the batter.
4. If using chopped nuts, sprinkle about 1/4 cup chopped pecans or walnuts on top before baking.

5. Bake for 30–35 minutes at 350°F, start checking at 25 minutes, until the liquid is mostly absorbed and the center is slightly moist.

   

6. Let cool for about 5 minutes.
7. Cut into 6 slices.

Tips for Perfect Texture

My top tip? Watch the bake closely toward the end. You want the liquid mostly absorbed but the center should stay a little moist. That moist center is key to the cozy, comforting texture you want in pumpkin baked oatmeal. Prefer single-serve portions with that same tender middle? Try Protein Pumpkin Muffins.

Grease your pan well
Testing showed the oats like to stick and caramelize a bit on the edges. Greasing your dish well helps you serve neat, beautiful slices without any hassle.

Mix-Ins and Easy Substitutions

All of these swaps work on a 1:1 basis unless noted. Refer to the recipe card quantities as you make swaps.

• Rolled Oats: The classic choice for chewy, hearty texture and fiber. Avoid instant oats here — they get mushy. Quick or old-fashioned rolled oats work great.
• Egg Whites: Boost protein and help bind everything together without that “eggy” flavor.
• Chia Seeds: Tiny nutrition powerhouses! They thicken the bake while adding healthy fats, fiber, and protein.
• Hemp Hearts: Great plant-based protein plus heart-healthy fats.
• Pumpkin Puree: Be sure it’s pure pumpkin, not pumpkin pie filling with added sugars and spices. Got extra puree? Put it to use in these Pumpkin Protein Balls.
• Milk: Adds creaminess and moisture. I love dairy or plant milks like almond, oat, or soy (soy’s protein content is close to cow’s milk).
• Coconut Sugar: Brown sugar or maple syrup can be swapped in. Expect slight flavor and moisture differences.
• Vanilla & Cinnamon: These bring warm, cozy flavors that make this pumpkin baked oatmeal sing.
• Chocolate Chips: Because everything’s better with a little chocolate! Use semi-sweet, dark, or milk chocolate options. Love the pumpkin + chocolate combo? Bake a batch of Pumpkin Protein Muffins with Chocolate Chips.
• Salt: Don’t skip it — salt brightens all the flavors, even sweet ones.
• Plain Non-Fat Greek Yogurt (for topping): Adds a creamy protein boost and balances the sweetness perfectly. Try mixing it with maple syrup for a lightly sweet glaze effect.

For some added crunch and nutrition, sprinkle about ¼ cup chopped pecans or walnuts on top before baking—and enjoy their toasty flavor.

Store, Freeze, and Reheat

This pumpkin baked oatmeal is super easy to keep on hand and warm up whenever you need it.

• Fridge: Store leftovers in an airtight container for up to 5 days. Perfect for busy mornings when you need a quick grab-and-go breakfast. Try high-protein egg bites if you want another portable option.
• Freezer: Once completely cooled, cut into slices, wrap individually in plastic wrap or foil, and freeze in a container or bag. They’ll keep up to 3 months. This same wrap-and-freeze method works well for a high-protein breakfast burrito, too.
• Reheating: You can eat it cold from the fridge (surprisingly tasty!) or warm it up. Microwave slices for 45-60 seconds, or thaw overnight if frozen and then reheat.

Answers to Common Questions

• Can I use instant oats? – Instant oats get too mushy and change the texture, so I recommend rolled oats (old-fashioned or quick rolled) for the best chewy bite.
• What if I don’t have egg whites? – Whole eggs work but will change protein and fat levels. For a vegan option, use flax or chia eggs (note: texture and protein will differ).
• How do I know when it’s done? – The edges should be golden and set, and the center mostly set but a little moist. Start checking around 25 minutes; it usually takes 30-35 minutes at 350°F.
• Can I make this vegan? – Yes! Swap egg whites with flax or chia eggs, use plant milk and yogurt. Protein content will be lower; for more plant-based, high-protein breakfast ideas, see these Vegan Breakfast Bowls.
• Can I reduce sugar? – Of course, cut the coconut sugar or swap with maple syrup, brown sugar, or a sugar substitute. Just keep an eye on sweetness and moisture.
• How should I store and reheat leftovers? – Keep in the fridge up to 5 days or freeze slices up to 3 months. Microwave refrigerated portions for 45-60 seconds; frozen slices take longer or require overnight thawing.
• Can I add nuts or other mix-ins? – Yes! Fold in or sprinkle about ¼ cup chopped nuts like pecans or walnuts, or toss in dried fruit and seeds. If adding big ingredients, tuck them near the top to toast.
• Can I halve the recipe or change the pan? – You can! Just adjust baking time, checking earlier if halving or later if using a deeper pan.
• Is canned pumpkin okay? – Yes, 100% pumpkin puree (canned or fresh) works best. Avoid pumpkin pie filling because it has added sugars and spices.
