Preheat Your Oven: Start by preheating your oven to 375°F (190°C). This is key for getting your casserole perfectly cooked.
Prepare the Potatoes: Peel and cube your potatoes into bite-sized pieces. Then, steam them in a pot until they are tender.
Sauté the Veggies: While the potatoes are cooking, heat a drizzle of olive oil in a skillet over medium heat. Add chopped onion and diced carrot, sautéing until they soften.
Add Broccoli: Toss in the broccoli florets and continue to cook for a few minutes until they turn a vibrant green.
Assemble the Casserole: In a greased baking dish, layer your tender steamed potatoes with the sautéed vegetables. Be sure to sprinkle 1 teaspoon of salt evenly over the top for flavor.
Mix and Drizzle: Drizzle some olive oil over the layers and mix everything gently so it combines beautifully.
Bake Time: Cover the dish with foil and pop it in the oven for about 25 minutes. After that, remove the foil and bake for another 15 minutes until golden.
Serve Hot: Take it out, let it cool slightly, and serve hot! You’re in for a treat!
