- 1/2 cup fresh breadcrumbs made from crustless Italian bread
- 2 pounds asparagus, trimmed
- 2 tablespoons unsalted butter
- 1 medium onion, finely chopped
- 1 cup freshly grated Parmesan cheese (about 3 ounces)
- 1/2 cup whole-milk ricotta cheese
- 1/4 cup all purpose flour
- 4 large eggs
- Butter eight 3/4-cup custard cups or soufflé dishes. Coat with breadcrumbs. Cut off asparagus tips. Cook tips in large saucepan of boiling salted water until crisp-tender, about 3 minutes. Drain; reserve tips and 1 cup cooking liquid. Coarsely chop asparagus stalks.
- Melt butter in large nonstick skillet over medium heat. Add onion; sauté until tender, about 6 minutes. Add stalks; sauté until crisp-tender, about 5 minutes. Add reserved asparagus cooking liquid. Cover; simmer until stalks are tender, about 12 minutes.
- Uncover; cook until liquid is absorbed, stirring often, about 5 minutes. Transfer to food processor; puree. Add Parmesan, ricotta and flour. Using on/off turns, process just until blended. Season with salt and pepper.
- Whisk eggs in bowl to blend. Add asparagus puree; whisk to blend. Stir in all but 16 asparagus tips. Divide custard among cups. Place cups in roasting pan. (Can be made 6 hours ahead. Cover; chill puddings and remaining asparagus tips.)
- Preheat oven to 350°F. Pour hot water into pan to come 1 inch up sides of cups. Bake puddings until set, about 35 minutes. Let stand 10 minutes. Invert onto plates. Garnish with asparagus tips.
