This one started because I had half a bunch of asparagus, a can of white beans, and absolutely no interest in doing real dishes. It turned into something I’ve made probably a dozen times since. The setup is simple — roasted asparagus with a ton of lemon and black pepper, smashed white beans on thick toast, and a barely-set egg on top. The whole thing comes together in under 30 minutes using just the toaster oven.
The asparagus is what makes it. At 425°F, the tips get these little crispy, almost-charred edges while the spears stay tender inside. You need a decent toaster oven baking sheet for this — something with a rim but low enough sides that air circulates around the spears properly. A pan that’s too deep will trap steam and you’ll end up with limp, sad asparagus.
The white bean mash is maybe my favorite part. It’s not hummus, it’s not a dip — it’s just beans mashed with garlic, lemon, and olive oil until they’re creamy and spreadable. Warm, it soaks into the toast just enough without making it soggy. If you’ve got a reliable countertop toaster oven, this is exactly the kind of recipe it was built for — high heat, small batch, done fast.
The egg on top is non-negotiable. Baked eggs in a toaster oven are genuinely easy and the yolk stays a little runny if you watch the time. Everything together — the crunch of the toast, the creamy beans, the crispy asparagus, and that yolk breaking over everything when you cut in — it’s just a really satisfying plate of food.
Toaster Oven Crispy Lemon Pepper Roasted Asparagus and White Bean Toast with Soft Egg and Parmesan
Golden, garlicky white bean toast topped with crispy lemon-pepper asparagus, a jammy egg, and shaved Parmesan — all done in the toaster oven in under 30 minutes.
Ingredients
Asparagus
White Bean Mash
Toast and Toppings
Instructions
-
Preheat your toaster oven to 425°F on the roast or bake setting. If yours runs hot, 415°F is fine.
-
Toss the asparagus with 1.5 tablespoons olive oil, the lemon zest, black pepper, and salt right on your baking pan. Spread them in a single layer — crowding them is what makes them steam instead of crisp, so don't do it.
-
Roast the asparagus for 10 to 12 minutes, until the tips are a little charred and the spears have some color on them. Thin asparagus goes fast, so check at 10 minutes.
-
While the asparagus roasts, make the bean mash. Warm the olive oil in a small saucepan over medium-low heat, add the garlic, and cook about 60 seconds until fragrant. Add the drained beans, lemon juice, salt, and a splash of water. Mash with a fork until it's mostly smooth but still a little chunky. Set aside off the heat.
-
Pull the asparagus out and slide the toaster oven down to 375°F. Toast your sourdough slices directly on the rack for 3 to 4 minutes, flipping once, until golden and sturdy enough to hold toppings without getting soggy. Set them on your serving plates.
-
Now for the eggs. Lightly oil a small oven-safe dish or a ramekin (or just a corner of the baking pan lined with foil). Crack both eggs in. Bake at 375°F for 5 to 6 minutes for a jammy, still-runny yolk, or 7 to 8 if you want it more set. Keep an eye on them — toaster ovens vary.
-
Spread a generous layer of white bean mash on each toast. Pile on the asparagus. Slide an egg on top of each one. Finish with shaved Parmesan, red pepper flakes if you're using them, and a squeeze of lemon over everything.
Notes
Thin asparagus is really the move here — the pencil-thin kind gets those crispy, slightly charred tips that thick spears never quite manage in a toaster oven. If your toaster oven is small and you can't fit the asparagus and the eggs at the same time, roast the asparagus first, then do the eggs. The bean mash holds fine at room temperature for 20 minutes, so don't stress about timing. Leftover bean mash keeps in the fridge for 3 days and is good on basically everything.
