This is one of the most delicious soups I've made to date. Its fresh tasting with the filling components of the beans and homemade veggie broth. Add some horseradish for a kick and the crunch of asparagus and radish its honestly spring in a soup. I am so excited for you to try it! It does take 1.5 hours to make and since we are all enduring lock down, no better time to try something new.
1 lb. dried large white beans (such as lima or gigante), soaked overnight, drained
1 onion, trimmed, peeled, halved through core
3 ribs celery, trimmed, halved
1 oz. dried shiitake mushrooms (about 10 large caps)
8 sprigs parsley, plus ¾ cup parsley leaves with tender stems
1 head of garlic, halved, plus 1 garlic clove, finely grated
1 Tbsp. plus 1 tsp. kosher salt, plus more
¾ cup plus 3 Tbsp. extra-virgin olive oil, plus more for drizzling, divided
¾ cup mint leaves
1 bunch radishes
1 bunch medium-size asparagus (about 1 lb.)
1 10-oz. bag frozen peas, thawed
8 thick slices country or sourdough bread
1 4" piece fresh horseradish root, peeled
1 lemon, cut into 8 wedges
Preheat oven to 300°. Combine beans, onion, celery, mushrooms, parsley sprigs, halved head of garlic, 1 Tbsp. salt, 3 Tbsp. oil, and 2 qt. water in a large Dutch oven. Bring to a simmer over medium-high heat, cover, and transfer to oven. Bake until beans are fully cooked, tender, and creamy through and through but as intact as humanly possible, about 1 hour, start checking every 10 minutes after the first 45 minutes.
Using tongs, fish out aromatics ( onion, celery, mushrooms, parsley sprigs, halved head of garlic) and discard. Season with salt. Be generous! Under-seasoned beans are barely worth eating. Let sit on stovetop, uncovered, until ready to serve.
While beans are cooking, make your pistou (a cold sauce made from cloves of garlic, fresh herbs, and olive oil) and prep the vegetables and garnishes. Using your sharpest knife, finely chop mint and ¾ cup parsley leaves. Transfer to a small bowl. Add ¾ cup oil, grated garlic, and 1 tsp. salt and stir to combine; set pistou aside.
Trim and wash radishes, then slice as thinly as possible into coins (a mandoline really helps here). Transfer radishes to a small bowl, cover with cold water, and chill until ready to use.
Wash asparagus and trim woody stems by bending each spear near the cut end until you find the place where it wants to break naturally. Cut off tips, then cut each tip in half lengthwise. Slice now-tipless stalks crosswise into thin coins. Toss asparagus coins and tips and peas in a medium bowl; set aside.
When you’re almost ready to serve the stew, return beans to a gentle simmer over medium heat, taking care not to stir too much—you don’t want to bust up those beans!
Generously drizzle oil into a large cast-iron skillet and heat over medium until shimmering. Working in two batches, fry bread slices until golden brown on both sides, about 2 minutes per side. Season with salt and transfer to a plate.
Once beans are simmering, add asparagus and peas and cook, stirring gently, until asparagus coins are barely cooked but still bright green and crunchy, about 2 minutes.
Drain reserved radishes. Place horseradish root on a plate with a Microplane (the way you’d serve Parmesan). Bring Dutch oven full of stew directly to the table. Serve with fried bread, pistou, radishes, lemon wedges, and horseradish alongside.
