Green Beans and Carrots in Thyme Infused Butter Sauce
Equipment
- Large Pot
- Skillet or sauté pan
- Slotted spoon
- Ice water bowl
- Serving dish
Ingredients
- 1 pound carrots peeled and sliced into thin, even sticks
- 1 pound green beans trimmed
- 6 tablespoons unsalted butter divided
- 2-3 sprigs fresh thyme or ½ teaspoon dried thyme
- 1 clove garlic crushed (optional for added aroma)
- salt and pepper to taste
- pinch lemon zest optional, for brightness
Instructions
- Bring a large pot of salted water to a boil. Add the carrot sticks and cook for 4-5 minutes, until just tender. Add the green beans to the pot and cook for an additional 3-4 minutes. Both vegetables should be tender but still vibrant in color. Drain the vegetables and transfer them to a bowl of ice water to stop the cooking process. Once cooled, drain and set aside.
- In a large skillet or sauté pan over low heat, melt 4 tablespoons of butter. Add the thyme sprigs and crushed garlic clove, allowing the flavors to infuse into the butter for 2-3 minutes. Be careful not to let the butter brown; keep it at a gentle heat to create a creamy sauce. Remove the garlic after infusing if preferred.
- Add the drained carrots and green beans to the pan, tossing gently to coat the vegetables in the thyme-infused beurre fondue. Season with salt and pepper to taste.
- Add the remaining 2 tablespoons of butter and allow it to melt into the sauce, coating the vegetables for a glossy finish. For a touch of brightness, sprinkle lemon zest over the vegetables just before serving.
Notes
