What You’ll Need

Imagine pulling together a dish without a last-minute grocery run. That’s the beauty of this recipe. Here’s what you’ll need:

• Eggs – the stars of the show, of course!
• Butter – for that rich, comforting flavor.
• Flour – to thicken up our luscious sauce.
• Gruyère cheese – because what’s a gratin without a cheesy top?
• Milk – to create the creamy béchamel.
• Nutmeg – just a dash for warmth.
• Onion – adds a subtle sweetness.
• White salt and pepper – to season everything just right.

How to Make Hard-Boiled Egg Gratin In A Bechamel Sauce

Ready to dive in? Here’s how to bring this cozy dish to life:

1. Start by hard-boiling the eggs. Bring a saucepan of salted water to a rolling boil, then gently add the eggs. Lower the heat and let them simmer for 10 minutes.
2. Once the eggs are done, place them into cold water until they’re just cool enough to handle. Here’s a little trick: roll them with your palm on a hard surface to crack the shell, then peel under a slow stream of running water. It works like a charm!
3. In a small frying pan, melt some butter over low heat. Add the onion and cook, stirring frequently, until they’re tender but not browned. Set aside.
4. Next, let’s make the béchamel sauce. In a medium heavy-bottomed saucepan, melt more butter over low heat. Stir in the flour and whisk for around 2 minutes without letting it color.
5. Whisk in the milk, bringing it to a boil while whisking constantly to avoid lumps. Season with nutmeg, salt, and pepper, then reduce the heat and let it simmer for 10 minutes. Keep whisking and scraping the pan to ensure nothing sticks.
6. Stir the cooked onions into the béchamel and let it all cook together for an additional 5 minutes.
7. Preheat your grill. Slice the eggs into 1 cm (0.4 inch) slices and start assembling. Spread a thin layer of the béchamel sauce at the bottom of your gratin dish.
8. Layer the egg slices over this sauce, covering them with the remaining béchamel. Sprinkle generously with grated Gruyère cheese.
9. Place the dish under the grill. Keep an eye on it and turn the dish if necessary to ensure an evenly golden, bubbly top. Serve immediately and enjoy the deliciousness!

Cook’s Notes

Let’s talk practical tips. First, don’t rush the béchamel sauce; whisk it patiently to avoid lumps. If you find the bechamel is too thick, a splash more milk can help loosen it up. This dish is best served right away when the cheese is melty and gooey, but if you do have leftovers, they can be stored in an airtight container in the fridge for up to two days. Reheat gently in the oven or microwave until warmed through.

Make It Your Own

This recipe is delicious as is, but here are a few ways to make it your own:

• Swap the Gruyère cheese for sharp cheddar for a more pronounced flavor.
• Add a layer of sautéed spinach between the eggs and the sauce for some greens.
• Substitute half of the milk with cream for an even richer béchamel.
• Sprinkle some crispy bacon bits on top before grilling for a smoky kick.
