  • Author: WAFA LI

Ingredients

• 1 lb (450g) baby potatoes, thinly sliced (about 3 cups)
• 1 lb (450g) fresh green beans, trimmed and cut into 1-inch pieces (or frozen, thawed)
• 1 tbsp olive oil
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 cup low-sodium vegetable or chicken broth
• ½ cup milk (dairy or plant-based)
• 2 tbsp cornstarch or arrowroot powder (to thicken)
• ½ tsp dried thyme
• ¼ tsp smoked paprika
• Salt & pepper to taste
• 1 cup shredded cheddar or Gruyère cheese
• Optional: ½ cup crispy fried onions for topping


Instructions

  1. Preheat oven to 375°F (190°C). Lightly grease a 9×9-inch or 2-quart baking dish.
  2. In a large pot of salted boiling water, cook sliced potatoes 5 minutes until slightly tender. Add green beans and cook 3–4 more minutes. Drain and set aside.
  3. In a skillet over medium heat, warm olive oil. Sauté onion 4–5 minutes until soft. Add garlic and cook 1 minute more.
  4. Stir in broth, milk, cornstarch, thyme, smoked paprika, salt, and pepper. Simmer 3–4 minutes, stirring constantly, until thickened into a creamy sauce.
  5. Pour sauce over the cooked potatoes and green beans. Toss gently to coat.
  6. Transfer mixture to the baking dish and spread evenly.
  7. Top with shredded cheese (and crispy onions if using).
  8. Bake 25–30 minutes, until bubbly and golden on top.
  9. Let cool 5 minutes before serving—perfect alongside roasted chicken or turkey!

A modern twist on classic green bean casserole—without canned soup and full of fresh flavor!

💡 Make it ahead: Assemble the night before, cover, and refrigerate. Add 5–10 minutes to bake time.
