90-Second Zero-Carb Mug Bread (Grain-Free & Keto-Friendly)

 

Ingredients

Ingredient	Measurement	Notes
Large Egg	1 whole	Room temperature mixes best
Melted Butter or Olive Oil	1 tablespoon	Adds moisture and rich crumb
Shredded Mozzarella or Cheddar	2 tablespoons	Melted finely for structure
Baking Powder	1/2 teaspoon	Gives the bread its lift
Grated Parmesan (Optional)	1 tablespoon	Adds savory depth and stability
Garlic Powder & Dried Herbs	1/4 teaspoon each	Optional, for savory bread
Pinch of Salt	To taste	Enhances overall flavor

Step-by-Step Instructions

1. Grease the Mug: Lightly coat the inside of a microwave-safe mug or wide-bottomed ceramic ramekin with butter or cooking spray.
2. Combine Ingredients: In the mug, whisk the egg and melted butter together with a fork until smooth. Stir in the baking powder, shredded cheese, grated parmesan, salt, and seasonings until a thick batter forms.
3. Microwave: Cook on high for 75 to 90 seconds. The bread will rise significantly above the rim and settle slightly once finished.
4. Unmold and Cool: Run a butter knife around the edge and tip the mug upside down onto a cutting board. Let it cool for 1 to 2 minutes.
5. Slice and Toast: Slice horizontally into 2 to 3 rounds. For the best texture, lightly toast the slices in a hot skillet with a dab of butter until golden brown.

Chef’s Tips for Best Results

• Use a Flat-Bottom Ramekin: For round sandwich slices similar to English muffins, use a small 4-inch ceramic ramekin instead of a tapered coffee mug.
• Oven Alternative: If you prefer not to use a microwave, bake the ramekin in a preheated oven at 180°C (350°F) for 12 to 15 minutes until golden and firm to the touch.
• Taming Any Egg Flavor: Toasting the sliced bread in a pan with butter or adding herbs (such as oregano, rosemary, or garlic) eliminates any lingering eggy aroma.
