Prep: Preheat the oven to 400°F (200°C). Line a 12 cup muffin pan with paper liners.
Combine wet ingredients: Add oats, brown sugar, Greek yogurt, oil and egg to a medium bowl and mix very well. Set aside for 5 minutes.
Mix dry ingredients: In the meantime, mix flour, salt, baking powder and baking soda in a large bowl until evenly combined.
Toss strawberries in flour: Mix the strawberries with 1-2 tablespoons of flour in a small bowl.
Combine the batter: Add the wet ingredients to the bowl with the dry ingredients and stir just until combined. Batter will be lumpy. Do not use a whisk! Fold in the strawberries with 2-3 stirs.
Bake the muffins: Evenly divide the muffin batter between the prepared muffin cups. Bake on the middle rack for 20 minutes or until a toothpick inserted into the middle comes out mostly clean.
Cool the muffins: Cool the muffins in the pan for 5-10 minutes, then remove and cool completely on a cooling rack.
oats: quick oats or old-fashioned both work; if using old-fashioned soak them for 5 minutes longer than the recipe indicates.
oil: any neutral vegetable oil works; please use one that's heat stable. Melted butter can be substituted.
strawberries: fresh and frozen both work; frozen are a little cheaper but need to be thawed for around 10 minutes so they can be safely diced.
Tips & tricks
Do not skip soaking the oatmeal: The oatmeal must be soaked in the wet ingredients. Otherwise the muffins will bake up flat.
Do not skip flouring the strawberries: Flouring the strawberry helps to keep them from sinking to the bottom of the muffins. It also helps to contain their juices so the muffins are less likely to stick to the liners.
My favorite kitchen hack: Use a cookie scoop to transfer the batter to the muffin cups - not only is it easy and mess-free, but it also helps to give the muffins a beautiful shape.
To freeze, put into a freezer bag and label with the name and date. Freeze for up to 3 months.To defrost, unpack and place on a wire rack on the counter for a couple of hours. Warm in the microwave for a few seconds, if desired.
