• 2 cloves garlic, minced (approx. 1 tsp / 5g)
• Optional: Fresh thyme sprigs for garnish
• Dairy & Fats:
• 2 tbsp (28g) unsalted butter
• 2 tbsp (15g) all-purpose flour
• 2 cups (480ml) whole milk or heavy cream (for extra richness in your cream of cheese sauce)
• 1 cup (110g) shredded Gruyère cheese, divided
• ½ cup (55g) grated Parmesan cheese, divided
• Seasonings:
• ½ tsp salt, or to taste
• ¼ tsp black pepper, or to taste
• ½ tsp dried thyme
• Topping:
• ¼ cup (20g) panko breadcrumbs
• 2 tbsp (20g) extra shredded Gruyère or Parmesan cheese
• Optional Add-ins:
• A pinch of cayenne pepper or a dash of hot sauce for a little kick
• Freshly chopped parsley or chives for garnish
• Equipment You'll Need:
  Large saucepan or Dutch oven
  Vegetable peeler
  Chef’s knife and cutting board
  Whisk
  9x13 inch (23x33 cm) baking dish or similar 2-quart gratin dish

Directions

1. Prep Your Chayote: First things first, get your chayote ready! Using a vegetable peeler, carefully peel the chayote. Cut them in half lengthwise and scoop out the small, soft seed in the center. Chop the chayote into ½-inch (1.25 cm) cubes. This size ensures even cooking.
2. Boil Until Tender: Place the cubed chayote in a large saucepan and cover with cold water. Add a pinch of salt. Bring to a boil, then reduce heat and simmer for 15-20 minutes, or until the chayote is fork-tender but not mushy. Drain well and set aside. You want them tender but not waterlogged to avoid a watery gratin.
3. Make That Béchamel Sauce: This is the heart of our cream of cheese gratin! In the same saucepan (no need to wash!), melt the butter over medium heat. Add the minced shallots (or onion) and cook until softened, about 3-4 minutes. Stir in the minced garlic and cook for another minute until fragrant. Sprinkle in the flour and whisk constantly for 1-2 minutes to create a "roux." This cooks out the raw flour taste. Gradually pour in the milk (or cream) while whisking vigorously to prevent lumps. Keep whisking until the sauce thickens and coats the back of a spoon, about 5-7 minutes. Remove from heat and stir in ½ cup (55g) of Gruyère and ¼ cup (27g) of Parmesan cheese until melted and smooth. Season with salt, pepper, and dried thyme. Taste and adjust if needed.
4. Combine Chayote & Sauce: Gently fold the drained, cooked chayote cubes into your creamy béchamel sauce. Make sure every piece is nicely coated with that delicious cooking with cream goodness.
5. Assemble & Top: Pour the chayote mixture into your prepared 9x13 inch (23x33 cm) baking dish, spreading it evenly. In a small bowl, combine the panko breadcrumbs with the remaining ½ cup (55g) Gruyère and ¼ cup (27g) Parmesan cheese. Sprinkle this cheesy breadcrumb mixture evenly over the top of the gratin.
6. Bake to Golden Perfection: Place the baking dish into a preheated oven for baking at 375°F (190°C). Bake for 25-30 minutes, or until the gratin is bubbly around the edges and the topping is beautifully golden brown. If the top isn't browning enough, you can pop it under the broiler for the last 2-3 minutes (watch carefully to prevent burning!). Let it rest for 5-10 minutes before serving, allowing the sauce to set.
