Ingredients You’ll Need

ingredients for creamy garlic and herb roasted winter squash

Look for squash with matte, unblemished skin; a glossy sheen signals under ripeness. Fresh herbs brighten the creamy sauce, but dried work in a pinch—just halve the quantity.

Step-by-Step Instructions

Preheat & Prep: Heat oven to 425 °F (220 °C). Lightly oil a 9×13-inch ceramic baking dish.
Season the Squash: Toss squash cubes with olive oil, salt, pepper, and a pinch of chili flakes. Spread in the dish; roast 20 min.
Make the Garlic-Herb Sauce: While squash roasts, melt butter in a skillet. Add garlic and cook 30 sec until fragrant. Whisk in flour, then gradually pour in milk and cream. Simmer until thick enough to coat a spoon. Stir in thyme, rosemary, and nutmeg.
Combine: Remove squash, lower oven to 375 °F (190 °C). Pour sauce over squash; fold gently to coat.
Top & Bake: Sprinkle cheeses and panko evenly. Return to oven 20–25 min until bubbly and golden.
Rest & Serve: Let stand 5 min to thicken. Garnish with extra herbs and a crack of black pepper.

Pro Tips for Silky-Smooth Results

Cut squash into ¾-inch pieces so they roast quickly but don’t turn to mush.
Warm milk in the microwave for 30 sec; cold liquid causes lumps.
Use freshly grated cheese—pre-shredded coatings inhibit smooth melting.
Broil the last 2 min for an extra-crispy crust—watch closely!
Add a handful of baby spinach before baking for a green boost.
