The first time I made this lemon blueberry breakfast bake, I thought cottage cheese and oats would never sing together.
They do—bright lemon, pillowy oats, and juicy blueberries make a morning that feels like dessert but behaves like fuel.
It’s high in protein, hands-off, and makes great leftovers for rushed weekdays or relaxed weekend brunches.
If you like make-ahead breakfasts that actually taste homemade, this one earns a regular spot in my rotation. Try a lemony twist if you want another citrusy comfort recipe.
Why You’ll Love This Recipe
- High-protein start to the day that keeps you full through morning meetings.
- Minimal hands-on time: mix, bake, and slice.
- Naturally sweetened option you can dial down or swap to maple.
- Portable, easily portioned for grab-and-go breakfasts.
- Versatile: works as a snack, breakfast, or light dessert.
The bake has a tender, slightly custardy interior from the cottage cheese and eggs, while the oats give it gentle chew and structure.
When fresh blueberries burst in the oven they create little pockets of jammy sweetness that contrast with the bright citrus zing.
The top browns lightly but never becomes dry; the result is moist and sliceable, not crumbly or dense.
“This recipe is a weekday miracle — lemony, filling, and my kids asked for seconds. I meal-prepped for the week and it stayed moist in the fridge.” — 5★ from Jenna, reader
Key Ingredients
Cottage cheese — Cottage cheese is the secret to a custardy, protein-rich bake without needing protein powder.
Use small-curd for a smoother texture and full-fat if you want extra richness; low-fat works fine if you’re watching calories.
A trusted grocery brand or a local farm-made cottage cheese gives the best flavor.
Rolled oats — Old-fashioned rolled oats provide structure and a chewy, comforting mouthfeel.
They absorb the liquids during baking and soften into a tender cake-like crumb.
Avoid quick oats here; they will become too mushy and change the texture.
Blueberries — Fresh blueberries add bursts of acidity and sweetness that balance the lemon and honey.
If using frozen, don’t thaw them fully—tossing them in dry oats before folding helps prevent streaking and sinking.
Choose firm, ripe berries for best results.
Eggs & lemon — Eggs bind and give lift, while lemon juice and zest brighten and cut the sweetness.
Freshly zested lemon has volatile oils that really pop in the finished bake; bottled lemon juice won’t give the same lift.
If you prefer a subtler citrus note, reduce zest to 2 teaspoons.
Full ingredient list:
- 1 cup cottage cheese
- 2 cups rolled oats
- 1 cup blueberries
- 1/4 cup honey or maple syrup
- 2 large eggs
- 1/4 cup lemon juice
- 1 tablespoon lemon zest
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
Step-by-Step Instructions
Step 1: Prepare and preheat
Preheat your oven to 350°F (175°C) and lightly grease an 8×8-inch baking dish or similar-sized pan.
I prefer a metal pan for more even browning; a glass pan works but may need an extra minute or two.
Pro Tip: Line the pan with parchment for easy slicing and cleanup.
Step 2: Combine the wet ingredients
In a large bowl, scoop in the cottage cheese, then add the honey or maple syrup, eggs, lemon juice, lemon zest, and vanilla.
Whisk or beat briefly until mostly smooth; small curds from the cottage cheese are fine and give pleasant texture.
Pro Tip: If you want an ultra-smooth base, pulse the cottage cheese and eggs in a blender first.
Step 3: Add the dry ingredients
Stir the rolled oats, baking powder, and salt into the wet mixture until everything is evenly combined.
The oats will soak up moisture as the batter rests briefly, which helps the final texture.
Pro Tip: Let the mixture sit 5 minutes before baking if your oats are very dry; they’ll hydrate and the bake will set better.
Step 4: Fold in blueberries
Gently fold in the blueberries, being careful not to crush them.
If using frozen berries, fold them straight from the freezer to reduce bleeding.
Pro Tip: Toss berries with a teaspoon of flour or oats before folding to keep them suspended in the batter.
Step 5: Bake until set
Pour the batter into the prepared dish and smooth the top with a spatula.
Bake in the preheated oven for 25–30 minutes, or until the center is set and the top is lightly golden.
Pro Tip: A toothpick inserted in the center should come out slightly moist but not wet; it will continue to set as it cools.
Step 6: Cool and slice
Let the bake cool for 10–15 minutes; this helps it firm up for cleaner slices.
Slice into squares or bars and serve warm or at room temperature.
Pro Tip: For neat slices, chill fully in the fridge and run a knife under hot water, then dry and slice.
Expert Tips for Success
- Temperature precision matters: If your oven runs hot, drop the temperature by 10–15°F and extend bake time. This prevents the edges from overbrowning while the center finishes.
- Use room-temperature eggs: Cold eggs lower the batter temperature and can lead to underbaked centers; take them out 15 minutes before mixing.
- Parchment lining is your friend: It makes slicing and removing bars simple, and keeps corners from sticking.
- Customize sweetness mindfully: Start with 1/4 cup honey or maple syrup, then taste the batter (raw eggs aside) and adjust next time. Citrus brightness makes the bake feel less sweet than it is.
- Avoid overmixing: Once the oats are added, stir just until combined. Overmixing can make the bake gummy and dense.
- Swap equipment for texture control: A metal pan gives crisper edges; glass retains heat and yields a slightly softer crust. Use what you prefer and adjust time by a few minutes.
- Troubleshooting weepers: If the top cracks or the center is wet, your oven may be too hot. Tent with foil and reduce temperature, then continue baking gently.
- Boost protein without ruining texture: Fold in 2 tablespoons of unflavored protein powder or swap half the oats for cooked quinoa; reduce added liquid slightly to compensate.
- How to test doneness visually: The edges will pull away slightly from the pan and the center will have a slight jiggle but not be liquid.
- Make it more custardy: Replace one egg with an extra quarter cup of cottage cheese or Greek yogurt for a creamier set.

Storage & Freezing
Fridge storage: Cool the bake completely before wrapping tightly with plastic wrap or transferring to an airtight container.
Stored in the fridge, it lasts up to 4–5 days and keeps well for weekday breakfasts.
Reheat in the microwave for 30–60 seconds per slice or warm in a 325°F oven for 10–12 minutes for a freshly baked feel.
Freezer storage: Slice into portions, place parchment between layers, and freeze flat in a single layer in a sealed container or freezer bag.
They’ll keep 2–3 months without major texture loss.
To reheat from frozen, thaw overnight in the fridge or reheat in a 350°F oven for 15–20 minutes until warmed through.
Defrost and reheat tips: For best texture, thaw in the fridge overnight then crisp in a toaster oven or warm briefly in a skillet.
If flavors seem muted after freezing, a quick squeeze of lemon or a drizzle of honey brightens them again.
Variations & Substitutions
Lemon swap-outs: Try orange zest and juice for a mellow citrus flavor, or lime for a tangier profile.
Blueberry alternatives: Use raspberries, blackberries, or chopped strawberries; reduce berries slightly if they’re very juicy.
Grain swaps: Replace up to half the rolled oats with quick-cook oats for a softer texture, or use gluten-free certified rolled oats to make the bake gluten-free.
Dietary swaps: For dairy-free, use a thick unsweetened yogurt alternative and a plant-based egg replacer (follow package ratios); note texture will differ.
Add-ins: Stir in 1/3 cup chopped nuts or 1/4 cup chia seeds for crunch and extra fiber, or fold in 1/2 cup shredded coconut for tropical notes.
Slight sweeteners change: Substitute maple for honey for deeper flavor, or reduce to 3 tablespoons and add a mashed banana for natural sweetness.

Frequently Asked Questions
Q: Can I make this in a muffin tin instead of a baking dish?
A: Yes. Spoon batter into a greased muffin tin and bake at 350°F for about 18–22 minutes.
Muffins will be thicker on the inside and may need a minute or two extra depending on your oven.
Q: Is this recipe suitable for meal prep?
A: Absolutely. It stores well in the fridge for up to 5 days and freezes into individual portions for quick reheating.
It’s ideal for packing into lunches or eating straight from the fridge with a dollop of yogurt.
Q: Can I use Greek yogurt instead of cottage cheese?
A: You can swap with full-fat Greek yogurt for a similar tang and protein boost.
Texture will be slightly smoother; reduce any extra milk or liquid to keep the bake from running.
Q: How do I prevent blueberries from sinking to the bottom?
A: Toss berries lightly in a teaspoon of oats or flour before folding them in to help suspend them in the batter.
Folding gently and baking promptly also minimizes sinking.
Q: Can I double the recipe?
A: Yes. Double all ingredients and bake in a 9×13-inch pan; add 8–12 minutes to the bake time and check for doneness with a toothpick.
Ensure even thickness so the center cooks through evenly.
