Celery Gratin

Celery Gratin is the sleeper hit of vegetable sides—creamy, savory, and unexpectedly elegant. It transforms celery from background player to center-stage comfort food. Here’s a hybrid protocol inspired by Taste of Home, Food Network, and Laughing Spatula.

🥬 Celery Gratin with Cheese & Crispy Crumbs

🧂 Ingredients:

• 8–10 celery ribs, trimmed and chopped
• 1 small onion, diced
• 2 tbsp butter (plus more for topping)
• 2 tbsp flour
• 1½ cups milk or half-and-half
• ½ cup heavy cream (optional for richness)
• 1 cup grated Swiss or Gruyère cheese
• ¼ tsp ground nutmeg
• Salt and pepper to taste
• ½ cup panko or fresh breadcrumbs
• Optional: celery leaves, thyme, chopped parsley

🔧 Instructions:

1. Sauté the base

In a large pan, melt butter. Sauté celery and onion until just tender (about 5 min). Drain excess liquid and transfer to a greased baking dish.

2. Make the cheese sauce

In the same pan, melt butter and whisk in flour to form a roux. Slowly add milk and cream, whisking until thickened. Stir in cheese, nutmeg, salt, and pepper.

3. Combine and layer

Pour cheese sauce over celery mixture. Toss breadcrumbs with melted butter and sprinkle on top.

4. Bake

Bake at 375°F (190°C) for 25–30 minutes until bubbly and golden. Garnish with celery leaves or herbs.

🌿 Optional Twists:

• Add fermented garlic paste or ramp vinegar to the sauce for wild depth
• Swap Swiss for smoked cheddar, vegan cashew cheese, or miso tahini
• Top with pine ash, nettles powder, or crispy shallots for texture
