These marinated and yogurt beets are like a modern take on mast-o laboo, which is an Iranian appetizer of chopped beets and tangy, thick yogurt. Think mast-o laboo deconstructed, with the addition of pistachios for an even creamier sauce to foil the vinegar-flavored beets with.
2 1/2 pounds small red beets, trimmed
4 thyme sprigs
2 teaspoons olive oil, divided
3 teaspoons salt, divided
1/4 cup orange juice (from 1 orange)
2 tablespoons red wine vinegar
3/4 cup roasted pistachios, plus 1 tablespoon chopped pistachios for garnish
1/4 cup olive oil
1/2 cup plain Greek yogurt
1. Make the beets: Preheat oven to 375F degrees. Toss together beets, thyme, 1 teaspoon oil, and 1/2 teaspoon salt in a roasting pan. Spread beets in pan; pour 1/2 cup water into pan. Cover pan with aluminum foil. Bake in preheated oven until beets are tender, about 1 hour. (Larger beets will take longer to cook.) Remove from oven. Reduce oven temperature to 350F degrees.
2. Remove beets from pan; let stand until cool enough to handle. Peel each beet to remove skin; discard skins. Cut beets into quarters. While beets are warm, transfer to a large bowl. Add orange juice, vinegar, remaining 1 teaspoon oil, and 1 teaspoon salt; toss to coat. Let stand 15 minutes. Toss beet mixture; taste and adjust seasonings, if needed. Set aside until ready to serve.
3. Make the pistachio yogurt: Spread pistachios evenly on a rimmed baking sheet. Bake at 350F degrees until lightly toasted, about 5 minutes. Transfer to a food processor; pulse until finely chopped, about 10 times. Add warm water; process until mixture is the consistency of chunky peanut butter, about 1 minute. With processor running, gradually drizzle in olive oil until mixture is mostly smooth and spreadable, about 30 seconds. Transfer mixture to a bowl; fold in yogurt and 1 teaspoon salt.
4. Spread yogurt sauce on a serving platter; top with beets. Garnish with chopped pistachios.
