First up, get those vegetables ready! Peel and chop your potatoes, carrots, parsnips, and butternut squash into roughly 1-inch pieces. I know, it feels like a lot of chopping sometimes, but it’s worth it. Try to keep them similar in size so they cook evenly. This is where I usually put on a podcast and just get into the zone, trying not to let bits of carrot fly everywhere. Rinse them well, too, especially the potatoes, to get rid of some starch.

Bring a large pot of salted water to a boil. Add the potatoes, carrots, and parsnips, and blanch for about 5-7 minutes until they're just tender-crisp. You don't want them mushy, just slightly softened. This step is crucial for even cooking in the oven, and honestly, I've skipped it before and ended up with some raw-ish bits. Drain them really well, then spread them out on a clean towel to dry a bit. We don't want watery sauce, do we?

In a large saucepan, melt the butter over medium heat. Add the minced garlic and cook for about a minute until fragrant – oh, that smell! Then, whisk in the flour and cook for another minute, stirring constantly, to create a roux. This is where the magic starts! Gradually whisk in the milk and vegetable broth until smooth. Keep whisking until the sauce thickens and starts to bubble, about 5-7 minutes. It should be thick enough to coat the back of a spoon.

Once the sauce is thick, stir in the fresh thyme, rosemary, a pinch of nutmeg, salt, and black pepper. Taste it! This is your moment to adjust the seasonings. I always add a little more pepper than I think I need, because, well, I love pepper. The sauce should be flavorful and well-seasoned, because it's going to carry all those lovely vegetables. Don't be shy here!

Gently fold the blanched vegetables (potatoes, carrots, parsnips) and the raw butternut squash into the creamy sauce. Make sure everything is nicely coated. Transfer this glorious mixture into a large, greased baking dish. I usually use a 9x13 inch dish, and it fills up nicely. Try to distribute the vegetables evenly so everyone gets a bit of everything. This is where my kitchen counter usually gets a little messy, but it’s all part of the process!

Sprinkle the shredded Gruyère cheese generously over the top. Pop it into a preheated oven at 375°F (190°C) and bake for 35-40 minutes, or until the vegetables are tender, the sauce is bubbly, and the cheese is golden brown and irresistible. The aroma filling your kitchen will be incredible, trust me. Let it rest for a few minutes before serving; it makes slicing a bit easier and lets the sauce settle.
