The Ultimate Keto Sandwich Hack: Steak & Egg ‘Bunwiches’!

Calling all my fellow sandwich lovers! If you’re living the keto lifestyle, you know the struggle is real when a sandwich craving hits. Forget spending hours baking complicated keto breads with a dozen specialty flours. The secret to a satisfying, bread-free sandwich is already in your fridge: eggs! These ingenious egg ‘buns’ are a game-changer—fluffy, sturdy, and ready in minutes.

This recipe is also my favorite way to transform last night’s steak dinner into a spectacular lunch. That leftover grilled steak gets a vibrant new life when paired with zesty chimichurri and nestled between two savory egg buns. Don’t have leftovers? No problem! A freshly grilled steak works just as beautifully, served hot or cold. Get ready to rediscover your love for sandwiches, the easy keto way!

Instructions

1. In a medium bowl, crack the eggs. Add the garlic powder, onion powder, salt, and pepper, and whisk until just combined.2. Drizzle the avocado oil into a large, non-stick frying pan. Before turning on the heat, use your fingers to grease the inside of the 8 mason jar rings. Place the greased rings flat-side down in the cool pan.3. Turn the heat to medium-low and let the pan warm for 1 minute. Carefully divide the egg mixture among the rings, pouring about ¼ cup / 60 ml into each one.4. Cover the pan and cook for 5 minutes, or until the eggs are fully set. Remove from the heat and let stand for 2 minutes.5. Use a spatula to lift the rings and eggs from the pan. Carefully pop the finished egg buns out of the rings.6. To assemble, place one egg bun on a plate. Spread it with 2 tablespoons of chimichurri, top with one-quarter of the sliced steak, and finish with a second egg bun. Repeat to make 4 sandwiches.7. Serve each sandwich with a side of 1 cup of mixed greens, drizzled with the remaining 2 tablespoons of chimichurri.
