What To Expect From This Recipe

• Taste: Your palate will first be greeted by the satisfying crunch and savory notes of salt and pepper, followed by the warm, aromatic depth of garlic and onion. The green beans retain a pleasant crispness while the potatoes become incredibly tender inside with a golden exterior, all infused with these harmonious flavors.
• Ease: This recipe truly couldn’t be simpler! The process involves just three straightforward steps: coating your fresh vegetables in quality olive oil, sprinkling them generously with our easy-to-find seasonings, and then letting your oven do all the hard work. Minimal fuss, maximum flavor!
• Time: From start to finish, you’re looking at an incredibly efficient cooking time. Prep work takes a mere 5 minutes, allowing you to get these delightful veggies into the oven quickly. The baking time is a hands-off 35-40 minutes, meaning you can have a wholesome, homemade side dish on the table in under an hour.

1. Step 1. Prepare the Vegetables: Begin by thoroughly washing your potatoes and green beans under cold running water. For the potatoes, slice them into uniform 1-inch quarters. This size is crucial for even cooking and ensuring they become tender and crispy at the same rate as the green beans. For the green beans, snip off any tough stems from their ends. If using fresh, make sure they are crisp and vibrant.

2. Step 2. Coat with Oil and Garlic: Transfer your prepared potatoes and green beans onto a large baking sheet. Drizzle them generously with olive oil and add the minced garlic. Using your hands or two large spoons, toss the vegetables thoroughly until every piece is evenly coated in the oil and garlic. This step is key for achieving that beautiful golden-brown crispness and infusing flavor.

3. Step 3. Prepare the Seasoning Blend: In a small bowl, combine your chosen dry seasonings: salt, ground black pepper, onion powder, and dried parsley. Give them a quick whisk or stir to ensure they are well mixed. This step ensures an even distribution of flavor.

4. Step 4. Season Evenly: Generously sprinkle the combined seasonings over all the olive oil-coated vegetables on the baking sheet. Toss everything once more with your hands or spoons, making sure the spices adhere evenly to every single potato piece and green bean. Spread the vegetables into a single layer across the baking sheet, ensuring they are not overcrowded, which helps them roast rather than steam.
5. Step 5. Bake to Perfection: Place the baking sheet into your preheated oven and bake for a total of 35-40 minutes. It’s important to stir the vegetables at the 20-minute mark to promote even browning and prevent sticking. After stirring, return them to the oven for the remaining 15-20 minutes. To test for doneness, gently pierce a potato piece with a fork; it should be tender all the way through, and the green beans should be crisp-tender and slightly blistered. Serve immediately and enjoy!

📌 Top Tips & Hacks for Perfect Roasting

• Thaw Frozen Green Beans Completely: If opting for frozen green beans, ensure they are fully thawed and patted dry before tossing them with oil and seasonings. Baking them from frozen will release too much moisture, causing them to steam instead of roast, leading to a soggy texture.
• Fresh Garlic is Key: While garlic powder can be used in a pinch, fresh minced garlic adds a superior depth of flavor and a touch of moisture to the vegetables. This helps prevent them from becoming overly dry or too crispy, contributing to a more balanced roasted texture.
• Don’t Overcrowd the Pan: This is a golden rule for roasting! Ensure your vegetables are spread in a single layer on the baking sheet, with a little space between each piece. If the pan is too crowded, the vegetables will steam and become soft rather than achieving those delicious crispy edges. Use two baking sheets if necessary.
• Uniformity is Essential: Cut your potatoes and any other root vegetables to roughly the same size (about 1-inch pieces). This ensures they cook evenly and are all tender at the same time.
• Parchment Paper for Easy Cleanup: Line your baking sheet with parchment paper for effortless cleanup. It also helps prevent sticking and promotes even browning.
• Hot Oven, Happy Veggies: Roasting at 375-400°F (190-200°C) is ideal for these vegetables. The high heat helps to caramelize their natural sugars and create that irresistible crisp exterior.
• Season Generously: Don’t be shy with the seasonings! A good coating of salt, pepper, garlic, and onion powder is what truly makes these roasted veggies shine.
• Check for Doneness: The cooking time can vary slightly depending on your oven and the size of your potato pieces. Always test with a fork to ensure the potatoes are tender before removing them from the oven.

Absolutely! This recipe is fantastic for meal prepping or preparing for a gathering. You can roast the green beans and potatoes ahead of time, then simply warm them up in the oven (or even a microwave for quicker reheating) when you’re ready to serve. They maintain much of their delicious flavor and texture, though they might lose a little of their initial crispiness.

Proper storage ensures your leftovers stay fresh and tasty.
Refrigerate: Store cooled roasted vegetables in an airtight container in the refrigerator for up to 5 days.
Freeze: For longer storage, these can also be frozen! Spread the cooled vegetables in a single layer on a baking sheet and freeze until solid, then transfer to a freezer-safe bag or container. They will keep well in the freezer for up to 3 months. Thaw overnight in the refrigerator before reheating.

Beyond the basic seasonings of garlic, onion powder, salt, and pepper, there are many ways to enhance green bean flavor!
– Aromatic herbs like dried oregano, thyme, or sage (as mentioned in variations) work wonderfully.
– A drizzle of rich balsamic glaze or a squeeze of fresh lemon juice after roasting will add a bright, acidic pop.
– For a nutty undertone, sprinkle with toasted sesame seeds or a dash of sesame oil.
– Adding a pinch of red pepper flakes offers a subtle spicy kick.
– Crispy bacon bits or toasted almonds are also classic, delicious additions.

Yes, you can! While the oven provides that signature crispy texture, a slow cooker offers a hands-off approach for a softer result. Simply combine all of the ingredients (potatoes, green beans, olive oil, seasonings) in your crockpot, ensuring they are well mixed. Set it to low for 4-5 hours, or high for 2-3 hours. Make sure to test the potatoes with a fork for tenderness to ensure they are fully cooked through before serving.

A large, heavy-duty metal baking sheet (often called a half-sheet pan) with a rim is ideal. The heavy material conducts heat evenly, and the rim prevents liquids or vegetables from sliding off. Avoid dark-colored pans if you’re prone to burning, as they tend to absorb more heat and cook faster. Lining with parchment paper is always recommended for non-stick results and easy cleanup.

Absolutely! This recipe is naturally vegan as written, as all ingredients (potatoes, green beans, olive oil, and spices) are plant-based. If you choose to add any of the suggested variations, simply ensure they are also vegan-friendly. For example, use nutritional yeast for a cheesy flavor instead of Parmesan, or omit bacon.
