onion
2-3 garlic cloves
1 cup heavy cream
1 rosemary sprig
3/4 tsp. Diamond Crystal or 3/8 tsp. Morton kosher salt, plus seasoning to taste
1/4 tsp. freshly ground black pepper, plus seasoning to taste
2 large bunches of Tuscan kale and/or Swiss chard (1–1 1/4 lb. total)
1/2 lemon
1/8 tsp. crushed red pepper flakes
3 oz. high-quality sharp cheddar cheese
1/4 cup breadcrumbs (panko or I like Schar GF)
1 tsp. extra-virgin olive oil
Preparation
2. While cream cooks, remove ribs from 4 medium bunches of (Tuscan) kale (I actually like cutting up the ribs and including them with my thousand head kale). Tear leaves into big pieces and wash. It’s okay if some water still clings to the leaves—this will help them wilt later. If you don’t have a bowl big enough to hold all of your greens, pile them on a baking sheet instead.
3. When cream is ready, pluck out rosemary sprig and discard. Finely grate zest of ½ lemon into cream and stir in ¼ tsp. crushed red pepper flakes.
5. Cut sharp cheddar cheese into ¼"-thick slices (or just used shredded). Combine bread crumbs, extra-virgin olive oil, season with salt and pepper, and add on top of kale. Bake at 350 until cheese is browned and bubbling and panko is toasted, 50–55 minutes.
