Baked Apple Oatmeal Greek Yogurt

My apartment was freezing that first November in my new place, the radiator clicking but not really doing its job. I craved something that would make the whole kitchen smell like comfort, something I could eat all week without getting bored. This baked oatmeal became my answer, bubbling away in the oven while I sat on the floor with a book, grateful for every bit of warmth it threw my way.

I brought this to a friend's brunch last winter, still warm from my oven, wrapped in a tea towel. Everyone kept asking what bakery I bought it from, which felt like the ultimate win. Now it's my go-to when I want to feed people something that feels special but actually took almost no effort.

Ingredients

• Old-fashioned rolled oats: Steel-cut won't work here, and instant oats turn to mush, so stick with the classic rolled variety for that perfect tender bite
• Milk: Dairy gives you the creamiest result, but unsweetened almond or oat milk work beautifully if that's your preference
• Eggs: These are what transform this from simple oats into something almost like a pudding, giving it structure and protein
• Maple syrup or honey: This provides just enough background sweetness without making it feel like dessert
• Butter or coconut oil: Adds richness and helps create that slightly crisp, golden edge on top
• Vanilla extract: Don't skip this, it's what makes everything taste like a treat instead of breakfast gruel
• Ground cinnamon and nutmeg: Warm spices that make the kitchen smell incredible while this bakes
• Baking powder: Just enough to give the oats a little lift, keeping the texture light rather than dense
• Salt: Essential for balancing the sweetness and making all the flavors pop
• Apples: Gala or Honeycrisp are perfect here, holding their shape while becoming tender and fragrant
• Lemon juice: Keeps the apples from browning and adds a bright note that cuts through the richness
• Brown sugar: Optional, but it helps the apples caramelize slightly as they bake
• Greek yogurt: The cool, tangy contrast against warm, spiced oats is what makes each bite feel complete
• Walnuts or pecans: Toasted nuts add crunch and make this feel like something you'd order at a cafe

Instructions

Get your oven ready:

Preheat to 350°F and grease your baking dish with butter or oil, paying attention to the corners

Whisk the wet ingredients:

Beat eggs, milk, melted butter, maple syrup, and vanilla until everything's fully incorporated and slightly frothy

Build the oat base:

Fold in the oats, baking powder, spices, and salt, stirring until the dry ingredients are completely moistened

Prep the apples:

Toss diced apples with lemon juice, brown sugar, and cinnamon until every piece is lightly coated

Bring it together:

Gently fold the seasoned apples into the oat mixture, being careful not to overmix

Transfer to the dish:

Pour everything into your prepared baking dish and use a spatula to spread it evenly

Bake until golden:

Let it bake for 35 to 40 minutes until the top is golden brown and the center is set but still slightly moist

Let it rest:

Cool for at least 5 minutes, which helps it set up and makes serving much easier

Make the topping:

Stir Greek yogurt with maple syrup until smooth and pourable

Serve it up:

Cut into squares and top with that creamy yogurt mixture, adding toasted nuts if you want extra crunch

This became my Sunday ritual during a particularly stressful semester, something I could put in the oven and forget about while I graded papers. Knowing I had breakfast handled for the week made Monday mornings feel less daunting, and there was something deeply grounding about starting each day with something homemade.

Make It Your Own

Once you've got the basic method down, this recipe becomes a canvas for whatever you're craving or whatever's in your fruit bowl. I've swapped pears for apples when that's what I had, and tossed in dried cranberries during winter when fresh fruit felt lackluster. The ratios stay the same, but the personality changes completely.

Storage and Meal Prep

This is one of those magical breakfasts that actually tastes better on day two, after the flavors have had time to meld and develop. Store it in the refrigerator in an airtight container for up to four days, and when you're ready to eat, just warm individual portions in the microwave for about 45 seconds. The texture remains remarkably intact, unlike so many meal prep options that turn soggy or dry.

Serving Suggestions

While Greek yogurt is the classic topping, I've also served this with a dollop of cottage cheese for extra protein, or even a scoop of vanilla ice cream when I'm feeling indulgent. A cup of Earl Grey tea alongside feels like the proper accompaniment, but honestly, this works just as well grabbed cold from the fridge on your way out the door.

• Add a drizzle of almond butter over the top for healthy fats
• Sprinkle extra toasted nuts just before serving for maximum crunch
• Reheat with a splash of milk if it's been in the fridge for a few days

There's something profoundly satisfying about starting your day with something that feels like a hug from the inside out, especially when you know you made it yourself. May your kitchen smell like cinnamon and may your week be just a little easier for having this ready.

Recipe FAQs

→ Can I make this ahead of time?

Absolutely. This baked oatmeal keeps well refrigerated for up to 4 days. Simply reheat individual portions in the microwave for 1-2 minutes before serving. The flavors actually develop and improve overnight.

→ What type of apples work best?

Firm apples like Granny Smith, Honeycrisp, or Braeburn hold their shape nicely during baking. Softer varieties like Golden Delicious or Gala will become more tender and almost sauce-like—both textures work beautifully.

→ Can I use steel-cut oats instead?

Steel-cut oats require significantly more liquid and longer baking time, so they're not recommended for this specific recipe. Stick with old-fashioned rolled oats for the best texture and consistency.

→ Is this suitable for freezing?

Yes. Cut into individual portions, wrap tightly in plastic and foil, then freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

→ How do I make this dairy-free?

Replace dairy milk with almond, oat, or soy milk. Use coconut oil instead of butter, and swap Greek yogurt with coconut yogurt or a dairy-free alternative.
