How to Make Lemon Poppy Seed Baked Oatmeal

Preheat your oven to 350°F (175°C). This ensures a perfect baking environment for your delicious Lemon Poppy Seed Baked Oatmeal.
Whisk Together the eggs, maple syrup, Greek yogurt, almond milk, lemon juice, lemon zest, and vanilla in a large mixing bowl until fully combined. Together, they create a creamy and flavorful base.
Stir in the quick oats, poppy seeds, baking powder, and sea salt until evenly mixed. This will provide the delightful texture and flavor that makes every bite special.
Pour the mixture into a greased 9×9 baking pan, making sure the ingredients are evenly spread. This step ensures even baking and a luscious finish.
Bake for 30-35 minutes, checking in on the center—it should be set yet soft. This bake time allows it to rise to a golden brown perfection.
Cool the oatmeal before glazing; mix together powdered sugar and lemon juice until you reach your desired consistency. Allowing it to cool makes slicing much easier.
Drizzle the glaze over the cooled oatmeal or serve it on the side for guests to add as they wish. This touch adds sweetness and brightness to every bite.

Optional: Top with fresh berries or a dollop of yogurt for added flavor and creaminess.

Lemon Poppy Seed Baked Oatmeal Recipe FAQs

How do I select the right lemons for my baked oatmeal?
Absolutely! When choosing lemons, look for ones that are bright yellow with a smooth, firm skin. Avoid any with dark spots or wrinkles, as these can indicate overripeness. Ideally, you want lemons that yield slightly when pressed, which means they are juicier.

How long can I store Lemon Poppy Seed Baked Oatmeal in the refrigerator?
You can store your delicious baked oatmeal in an airtight container in the refrigerator for up to 7 days. Just make sure it’s completely cooled before placing it in the container to retain moisture and flavor.

Can I freeze Lemon Poppy Seed Baked Oatmeal? How do I do it?
Very much so! To freeze, wrap individual slices tightly in plastic wrap, then place them in a freezer-safe bag. They can last for up to 3 months. When you’re ready to enjoy, simply thaw in the fridge overnight and reheat in the microwave or oven until warm.

My baked oatmeal turned out dry; why could that be?
If your baked oatmeal is dry, it may have been overcooked. Always check for doneness in the center just before the minimum baking time is up. The center should be set but soft. Also, try to make sure the oatmeal mixture is well-combined before baking, as uneven mixing can cause different parts to cook at varied rates.

Are there any allergy considerations with this recipe?
Yes! This Lemon Poppy Seed Baked Oatmeal contains ingredients like eggs and dairy (Greek yogurt and almond milk), which can be allergens. If preparing for someone with allergies, you can easily substitute eggs with flax eggs and use plant-based yogurt for a dairy-free option. Always check labels for any other allergens in ingredients such as maple syrup or powdered sugar.
