Ingredients
| Ingredient | Quantity |
|---|---|
| Mixed vegetables (potatoes, cauliflower, broccoli, carrots) | 4 cups, chopped |
| Unsalted butter | 3 tablespoons |
| All-purpose flour | 3 tablespoons |
| Milk (whole or plant-based) | 2 cups |
| Grated cheese (Gruyère, cheddar, or vegan alternative) | 1 ½ cups |
| Garlic, minced | 2 cloves |
| Breadcrumbs | ½ cup |
| Salt | 1 teaspoon |
| Black pepper, freshly ground | ½ teaspoon |
| Nutmeg, grated (optional) | ¼ teaspoon |
| Fresh herbs (thyme or parsley), chopped | 2 tablespoons |
Equipment
- Large pot for boiling vegetables
- Medium saucepan for béchamel sauce
- Whisk
- Mixing bowls
- Grater for cheese
- Baking dish (9×9 inch or similar)
- Measuring cups and spoons
- Oven mitts
- Knife and cutting board
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease your baking dish with butter or oil.
- Prepare the vegetables: Chop the potatoes, cauliflower, broccoli, and carrots into bite-sized pieces. Bring a large pot of salted water to a boil and blanch the vegetables for 5-7 minutes until just tender. Drain well and set aside.
- Make the béchamel sauce: In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.
- Whisk in the flour and cook for 2-3 minutes, stirring constantly to form a smooth roux. This step is crucial for a creamy texture without lumps.
- Slowly add the milk while whisking vigorously to prevent lumps. Continue cooking and whisking until the sauce thickens and coats the back of a spoon, about 5-7 minutes.
- Remove from heat and stir in 1 cup of the grated cheese, salt, pepper, nutmeg, and chopped herbs. Taste and adjust seasoning as needed.
- Combine vegetables and sauce: Gently fold the cooked vegetables into the béchamel sauce until evenly coated.
- Transfer the mixture to your prepared baking dish, spreading it out evenly.
- Top with remaining cheese and sprinkle breadcrumbs evenly over the surface for a crunchy topping.
- Bake in the preheated oven for 25-30 minutes until the top is golden brown and bubbling.
- Remove from the oven and let it cool for 5 minutes before serving. This helps the sauce set slightly for easier plating.
Tips & Variations
Tip: For extra flavor, try adding sautéed onions or mushrooms to the vegetable mix before combining with the sauce. A pinch of smoked paprika or mustard powder in the béchamel can also add depth.
Variation: Swap out the mixed vegetables for seasonal options like zucchini, sweet potatoes, or Brussels sprouts. For a vegan version, use plant-based butter, non-dairy milk, and a vegan cheese alternative.
You can also explore different herb combinations such as rosemary or dill.
Pro Tip: To get a perfectly crispy topping, broil the au gratin for the last 2-3 minutes but watch carefully to avoid burning.
