Sweet Potato & Green Bean Tray Bake Ingredients
For the Vegetables
- Sweet Potatoes – Their natural sweetness and creamy texture make them a staple in this dish; feel free to substitute with butternut squash for a different flavor.
- Green Beans – These add a satisfying crunch and essential nutrients; asparagus or broccoli can be delightful alternatives.
For the Seasoning
- Extra Virgin Olive Oil – This is key for beautifully roasting the veggies while imparting rich flavor; you can reduce the amount for a lighter dish or use cooking spray instead.
- Garlic Powder – For a savory kick without the fuss of chopping fresh garlic; minced garlic is a great substitute if you prefer it fresh.
- Onion Powder – It provides depth and flavor; consider swapping it with finely chopped onions for added texture.
- Smoked Paprika – It brings a warm, smoky essence to the dish; if you don’t have smoked, regular paprika will work just as well.
- Salt and Pepper – Essential for seasoning; adjust to your taste for the perfect balance of flavors.
- Lemon Juice – Adds a bright, fresh finish; vinegar can substitute in a pinch for zest.
- Parmesan Cheese (optional) – A salty touch of richness; if you’re keeping it dairy-free, nutritional yeast makes a fantastic alternative.

Step‑by‑Step Instructions for Sweet Potato & Green Bean Tray Bake
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This temperature is perfect for roasting your sweet potatoes and green beans, ensuring they become beautifully caramelized and tender. While the oven heats up, gather your ingredients and equipment, including a large bowl and a baking sheet, to streamline the process.
Step 2: Prepare the Vegetables
In a large bowl, take your diced sweet potatoes and trimmed green beans and combine them. The sweet potatoes will bring natural sweetness, while the green beans add a vibrant crunch. Mix the vegetables thoroughly, making sure they are evenly distributed for even cooking, as this Sweet Potato & Green Bean Tray Bake relies on their perfect blend of flavors.
Step 3: Add Seasonings
Drizzle olive oil over the sweet potato and green bean mixture, then sprinkle in garlic powder, onion powder, smoked paprika, salt, and pepper. Use your hands to toss everything together until the veggies are well coated with the seasoning and oil. This will create a luscious layer of flavor that enhances every bite of your tray bake.
Step 4: Arrange on the Baking Sheet
Spread the seasoned vegetables evenly on a baking sheet in a single layer. This arrangement is crucial for achieving optimal roasting, allowing the sweet potatoes to caramelize beautifully while keeping the green beans crisp. Make sure not to overcrowd the pan; a little space goes a long way in ensuring even cooking.
Step 5: Roast the Vegetables
Place the baking sheet in the preheated oven and roast for 25–30 minutes. Halfway through the cooking time, stir the vegetables gently to promote even browning. Look for the sweet potatoes to turn golden and soft, while the green beans should maintain a vibrant color and tender crunch. The delightful aroma will fill your kitchen!
Step 6: Finish with Lemon Juice
Once cooked, carefully remove the tray bake from the oven. Drizzle fresh lemon juice over the vegetables for a zesty finishing touch. If you like, sprinkle Parmesan cheese on top for added richness. Mix everything gently to combine the flavors one last time before serving this delightful Sweet Potato & Green Bean Tray Bake to your family.

Make Ahead Options
These Sweet Potato & Green Bean Tray Bake preparations are perfect for busy weeknights and meal prep enthusiasts! You can chop the sweet potatoes and green beans up to 24 hours in advance; simply store them in an airtight container in the refrigerator to keep them fresh and vibrant.
