Cook the onion and garlic: Lower the heat to medium. Add 1 medium onion (chopped) and 2 cloves garlic (grated).Cook for 3–4 minutes, stirring often, until the onion softens. Add a splash of olive oil if the skillet looks dry.
Make the sauce: Meanwhile, whisk together 1½ cups vegetable broth, 2 tablespoons all-purpose flour, 1 tablespoon Dijon mustard, 1 tablespoon soy sauce, 1 teaspoon smoked paprika, and 1 teaspoon dried thyme.Mix until smooth, with no flour lumps.
Add the beans and simmer: Pour the sauce into the skillet and stir in 2 cans butter beans.Bring to a gentle simmer and cook for 5 minutes, stirring occasionally, until the sauce thickens and the beans are heated through.If too thick, add a splash of broth or water.
Finish and serve: Turn off the heat and wait until the sauce stops bubbling.Stir in ½ cup Greek yogurt and 2 tablespoons fresh parsley (chopped) until creamy.Taste and adjust the seasoning. Serve warm with crusty bread, egg noodles, rice, or mashed potatoes.

Avoid lumps: Whisk flour into cold broth until smooth.
Stir gently: Keep the butter beans from breaking apart.
Simmer gently: Avoid boiling the sauce too vigorously.
Add yogurt off the heat: Wait until the sauce stops bubbling to prevent curdling.
