PREPARATION SUGGESTIONS
ROASTED
Quarter radishes and roast at 425°F with olive oil, salt, and pepper for 20-25 minutes. They lose their peppery bite and taste like roasted potatoes.
RAW IN SALADS
Slice thin and add to salads for a peppery crunch. Pairs well with creamy dressings that balance the spice.
BUTTER-BRAISED
Sauté halved radishes in butter until tender and caramelized. The butter mellows the peppery flavor beautifully.
PICKLED
Quick-pickle in vinegar, salt, and a pinch of sweetener. Adds tangy crunch to tacos, sandwiches, and salads.
RADISH CHIPS
Slice thinly, toss with oil and seasonings, then bake at 375°F until crispy. A crunchy, low-carb snack.
MASHED
Boil until tender, then mash with butter, cream cheese, and herbs. A surprisingly good keto mashed potato substitute.
