Ingredients
-
2 1/2 lbs medium beets (about 7-9, 2-1/2-inch in diameter)
-
4 tablespoons unsalted butter
-
1 medium Spanish onion, cut into 1/4-inch-thick rings (about 8 oz.)
-
1/4 cup maple syrup
-
1 tablespoon fresh orange juice
-
1 1/2 teaspoons grainy mustard
-
1/2 teaspoon grated orange zest
-
1/4 teaspoon fresh ground pepper
Instructions
- Heat oven to 300 degrees. Butter baking dish large enough to fit beets in single layer.
- Scrub beets and trim tops to 1 inch. Place beets in prepared dish and cover. Bake until tender when pierced with fork, about 1 hour. Transfer to colander and cool briefly under cold running water. When cool enough to handle, slip off skins. Slice 1/4" thick (about 3-1/2 cups).
- Heat 2 T. butter in large heavy skillet over medium-high heat. Add onion and saute until somewhat tender but not browned, 2-3 minutes. Remove from skillet.
- Combine remaining 2 T. butter, the syrup, orange juice, mustard, orange zest, and pepper in same skillet. Heat over medium heat to boiling. Add beets and onions; cook, turning frequently with spatula, until syrup is absorbed and vegetables are glazed, about 4 minutes. Serve at once.
