• 2 large slices sourdough bread
• 1 tablespoon unsalted butter (for toasting)
• 1 ripe avocado
• 1 teaspoon lemon juice
• Salt and pepper, to taste
• 1 medium tomato, sliced
• 1 cup mixed greens (e.g., arugula, baby spinach)
• 4 slices smoked bacon (substitute with vegetarian bacon if desired)
• 2 large eggs
• Fresh chives, chopped (optional)
• Crushed red pepper flakes (optional)

Step 1

Preheat a skillet over medium heat. Add bacon and cook until crispy, about 5–7 minutes. Transfer to a paper towel-lined plate.

Step 2

While bacon cooks, lightly butter both sides of the sourdough slices. Toast in a separate skillet or toaster until golden brown.

Step 3

In a small bowl, mash avocado with lemon juice, salt, and pepper.

Step 4

Spread mashed avocado evenly over the toasted sourdough.

Step 5

Layer each slice with mixed greens, tomato slices, and crispy bacon.

Step 6

Heat a nonstick skillet over medium-low heat. Crack eggs into the pan and cook sunny side up until whites are set but yolks remain runny, about 3–4 minutes.

Step 7

Carefully slide one egg onto each stack.

Step 8

Garnish with chopped chives and red pepper flakes, if desired. Serve immediately.

For the perfect runny egg, cook on medium-low heat and cover the pan briefly to help the whites set without overcooking the yolk. When prepping ingredients, slice the tomatoes relatively thin to make the stack easier to eat. The avocado mash can be prepared slightly ahead of time if you add a little extra lemon juice to prevent browning.

For a vegetarian version, simply substitute the bacon with plant-based bacon or smoked tempeh. If you prefer a dairy-free option, use plant-based butter for toasting the bread. For extra flavor, consider adding a slice of cheese like sharp cheddar or pepper jack between the tomato and bacon layers. You could also incorporate herbs like basil or cilantro into the avocado mash for a fresh twist.

Serve this breakfast stack with a side of roasted breakfast potatoes or fresh seasonal fruit for a complete meal. For a special brunch, pair with a light mimosa or freshly squeezed orange juice. If you're serving for a group, consider setting up a build-your-own breakfast stack bar with all the components laid out for guests to customize their perfect stack.
