Cheesy Kale & Mushroom Strata

In the beginning, there was kale. From it arose the others, cauliflower, Brussels sprouts, cabbage, broccoli, collard greens, mustard, kohlrabi, rutabaga, turnips and Bok choy.

Kale is an ancient vegetable that has been enjoyed by humans for centuries. It is thought to have originated in Asia Minor and was brought to Europe by traders and travelers. Kale was a popular crop in medieval times and was often grown in monastery gardens.

In the 18th century, kale became even more popular after it was introduced to North America. There are several different types of kale, each with its own unique flavor and texture. Curly kale is the most common type, and it has a slightly bitter taste. Tuscan kale is a bit sweeter and more tender than curly kale, while Russian kale is the most robust and flavorful of all the varieties.

Kale holds its texture well when cooked, and it can be steamed, stir-fried, roasted, or eaten raw. You can blend it into smoothies, roast it to make kale chips, wilt it into soup, mash it with potatoes or turn it into pesto. You may want to remove the middle rib by hand or with kitchen shears because it can be tough, fibrous and taste bitter.

North Americans know kale well, along with being eaten it is often used to adorn the self-service salad bars across the land, displacing other green adornments because of its resistance to wilting. 

Brion & I enjoyed this cheesy kale and mushroom strata with some roasted sausage.

Instructions

1. The day before, prepare the strata so it can refrigerate over night. Preheat the oven to 300ºF. Tear the bread into 1 1/2-inch pieces and spread them out over a large baking sheet. Bake the bread chunks in the oven for 8-10 minutes, stirring once half-way through, to partially dry the bread.
2. Meanwhile, slice the mushrooms, then add them to a large skillet with the butter, minced garlic, some salt and pepper. Sauté the mushrooms over medium heat until they release all their moisture and begin to brown (about 5-7 minutes).
3. Remove the cooked mushrooms from the skillet and add the kale & leeks along with a couple tablespoons of water (this helps the kale wilt). Sauté the leeks & kale with some salt & pepper (2-3 minutes).
4. Coat the inside of a 12 cup (10 x 10-inch) casserole dish with butter or non-stick spray. Layer half of the dry bread chunks in the bottom of the dish, then top with half of the mushrooms, half of the kale, and half of the Gruyere. Wiggle the ingredients down between the bread chunks a bit, then repeat all the layers a second time.
5. In a large bowl, whisk together the eggs, milk, Dijon and 1/4 tsp each salt & pepper. Pour the egg mixture over the prepared strata, making sure to drizzle over every surface of the strata, rather than just pouring in one spot. Sprinkle with parmesan cheese. Cover the strata and refrigerate for 8-24 hours.
6. The next day, allow the strata to sit at room temperature for 30 minutes. Preheat the oven to 350ºF. Bake the casserole for 50 minutes, or until the internal temperature reaches 160 F. and the top is deeply golden brown.
7. Let the strata rest for 10 minutes, then slice into six pieces and serve!
