Follow these step-by-step instructions to bake a batch of perfect Cheese & Spinach Breakfast Muffins. We’ve broken down each step to ensure clarity and ease, even for beginner bakers.

Step 1: Preheat Your Oven and Prepare Muffin Tin

Begin by preheating your oven to 375°F (190°C). This is crucial for even baking and ensuring the muffins rise properly. While the oven is heating up, prepare your muffin tin. You can either grease a 12-cup muffin tin generously with cooking spray or line it with paper muffin liners. Liners make for easy cleanup and prevent the muffins from sticking, while greasing directly can create a slightly crisper edge on the muffins. Choose whichever method you prefer based on your desired texture and cleanup preference. Setting this up at the start ensures you’re ready to bake as soon as the batter is prepared.

Step 2: Prepare the Spinach

Next, we need to prepare the spinach. If you’re using fresh spinach, which is highly recommended for the best flavor and nutritional benefits, wash it thoroughly under cold running water to remove any dirt or grit. Once washed, you need to wilt the spinach slightly to reduce its volume and release excess moisture. There are a couple of ways to do this. The quickest method is to place the spinach in a microwave-safe bowl with a tablespoon of water, cover it, and microwave on high for 1-2 minutes, or until the spinach is just wilted. Alternatively, you can sauté the spinach in a dry skillet over medium heat for a few minutes, stirring occasionally, until it wilts down. Once wilted, immediately transfer the spinach to a colander and press out as much excess water as possible. This step is vital to prevent soggy muffins. After removing the excess water, roughly chop the spinach into smaller pieces. This ensures it distributes evenly throughout the muffin batter and you get a nice bite of spinach in every muffin. Set the prepared spinach aside.

Step 3: Combine Dry Ingredients

In a large mixing bowl, whisk together the dry ingredients. This includes the all-purpose flour, baking powder, salt, onion powder, and garlic powder. Whisking is important as it not only combines the ingredients but also aerates the flour, leading to lighter muffins. Ensure the baking powder is evenly distributed throughout the flour mixture, as this is responsible for the rise and fluffiness of the muffins. The onion and garlic powder add a subtle savory flavor base that complements the cheese and spinach perfectly. Set the bowl of dry ingredients aside.

Step 4: Combine Wet Ingredients

In a separate medium-sized bowl, whisk together the wet ingredients. This includes the eggs, milk, and vegetable oil. Whisk until the eggs are well beaten and the mixture is smooth and homogenous. The eggs provide structure and richness, the milk adds moisture, and the vegetable oil contributes to the tenderness of the muffins. Make sure the wet ingredients are thoroughly combined to ensure they emulsify properly and create a smooth batter when combined with the dry ingredients.

Step 5: Combine Wet and Dry Ingredients

Now it’s time to combine the wet and dry ingredients. Pour the wet ingredients into the bowl of dry ingredients. Using a spatula or a wooden spoon, gently fold the wet and dry ingredients together until just combined. It’s crucial not to overmix the batter at this stage. Overmixing can develop the gluten in the flour, resulting in tough, dense muffins. Mix only until the flour is just incorporated and you no longer see streaks of dry flour. A few lumps in the batter are perfectly fine and even desirable for tender muffins.

Step 6: Add Cheese and Spinach

Once the batter is just combined, gently fold in the shredded cheddar cheese and the prepared chopped spinach. Distribute them evenly throughout the batter, ensuring that every muffin will have a good amount of cheese and spinach. The cheddar cheese adds a wonderful savory flavor and melty texture, while the spinach provides a nutritious boost and a subtle earthy note. Fold these ingredients in gently to avoid overmixing the batter.

Step 7: Fill Muffin Tin and Bake

Spoon the batter evenly into the prepared muffin tin, filling each muffin cup about two-thirds to three-quarters full. This allows enough space for the muffins to rise without overflowing. If you’ve used muffin liners, ensure the batter is evenly distributed within each liner. Once the muffin tin is filled, place it in the preheated oven and bake for 18-20 minutes, or until a wooden skewer inserted into the center of a muffin comes out clean. The baking time may vary slightly depending on your oven, so it’s always best to check for doneness using the skewer test. The muffins should be golden brown on top when they are done.

Step 8: Cool and Serve

Once the muffins are baked, remove the muffin tin from the oven and let it cool in the tin for a few minutes. This allows the muffins to set slightly and makes them easier to remove from the tin. After a few minutes of cooling in the tin, carefully transfer the muffins to a wire rack to cool completely. Cooling them on a wire rack prevents the bottoms from becoming soggy. While they are delicious warm, they are also fantastic at room temperature or even cold, making them perfect for make-ahead breakfasts or snacks. Serve these Cheese & Spinach Breakfast Muffins warm or at room temperature and enjoy!
