Preheat the oven: Set to 400°F (200°C).
Lightly oil or spray a small baking dish to prevent sticking.
Prepare the avocados: Halve them lengthwise and remove the pits. Scoop out about 1–2 tablespoons of flesh from each half to create a larger well. Save the scooped avocado for topping or toast.
Stabilize the halves: To keep them from tipping, slice a tiny sliver off the rounded bottom of each half, or nestle them into a small baking dish with foil “nests.” They should sit flat so the eggs don’t spill.
Season the wells: Sprinkle the cavities with a pinch of salt and pepper for flavor from the inside out.
Add the eggs: Crack each egg into a small bowl first, then gently pour it into the avocado well.
If your eggs are large, pour off a little white so it fits. Aim to keep the yolk intact.
Bake: Place the dish on the center rack and bake for 12–16 minutes, depending on how set you like the yolk. Check at 12 minutes for a jammy yolk; add time for a firmer set.
Finish and top: Remove from the oven, season with more salt and pepper, and add your favorite toppings—cheese, bacon, herbs, or a dash of hot sauce.
Serve: Enjoy warm, as is, or with toast, a simple salad, or roasted potatoes.
