From the Test Kitchen

To complete this delicious, vegetarian casserole, you’ll be making a horseradish béchamel. Béchamel (a traditional French sauce made with flour, butter and milk) is a superior way to fuse a casserole’s distinct components—and flavors—together. Here, we’re tailoring the basic recipe by adding prepared horseradish (horseradish that has been grated and soaked in vinegar). The horseradish fives this dish a signature, peppery kick, perfectly balancing the light and earthy flavors of baked kale and cauliflower.

Prepare the ingredients:
1 Prepare the ingredients:

Preheat the oven to 400°F. Heat a medium pot of salted water to boiling on high. Wash and dry the fresh produce. Peel and mince the garlic. Pick the parsley leaves off the stems; discard the stems. Remove and discard the core of the cauliflower; cut the head into small florets. Remove and discard the stems of the kale; roughly chop the leaves.

Roast the cauliflower:
2 Roast the cauliflower:
Place the cauliflower on a baking sheet and drizzle it with about 1 tablespoon of olive oil or enough to thoroughly coat it and season with salt and pepper. Roast for 10 to 12 minutes, or until slightly browned, stirring halfway through.
Cook the egg noodles:
3 Cook the egg noodles:

While the cauliflower roasts, add the egg noodles to the pot of boiling water. Cook 5 to 6 minutes, or until just shy of al dente. Drain thoroughly and set aside. Rinse and wipe out the pot.

4 Make the béchamel sauce:

While the cauliflower continues to roast, in the same pot used to cook the egg noodles, melt the butter on medium heat. Once melted, add the garlic and cook, stirring frequently, 15 to 30 seconds, or until fragrant. Add the flour and cook, stirring frequently, 1 to 2 minutes, or until golden. Slowly whisk in the milk and 1 cup of water until no lumps remain. Bring the mixture to a boil; once boiling, reduce the heat to low. Simmer, whisking constantly, 3 to 6 minutes, or until thickened. Season with salt and pepper to taste.
