This vibrant green side is a crispy contrast to all that creamy and rich Thanksgiving fare. Tossed in olive oil and garlic, these roasted green beans are bold, bright, and just the right amount of fancy without trying too hard.
Ingredients
- 1 lb fresh green beans, ends trimmed
- 1 tbsp olive oil
- 2 cloves garlic, minced
- 1/2 tsp salt
- 1/4 tsp black pepper
Instructions
- Preheat the oven to 425°F and line a baking sheet with parchment paper.
- In a large bowl, toss the green beans with olive oil, garlic, salt, and pepper.
- Spread in a single layer on the prepared sheet and roast for 15–18 minutes, until tender and slightly blistered.
Quick Tip or Variation
Toss in sliced almonds or a sprinkle of lemon zest after roasting for a fresh, zippy finish.
2. Creamy Garlic Mashed Potatoes
No Thanksgiving is complete without mashed potatoes—but this version is buttery, garlicky, and fully make-ahead friendly. They stay fluffy and flavorful, even after reheating.
Ingredients
- 2 lbs Yukon Gold potatoes, peeled and chopped
- 4 tbsp butter
- 3 cloves garlic, minced
- 1/2 cup milk (or dairy-free alternative)
- 1 tsp salt
- 1/4 tsp black pepper
Instructions
- Place potatoes in a large pot and cover with cold water. Bring to a boil and cook until fork-tender, about 12–15 minutes.
- While the potatoes cook, melt the butter in a small saucepan over low heat. Add garlic and simmer gently for 2–3 minutes until fragrant.
- Drain potatoes and return to pot. Mash with the garlic butter, milk, salt, and pepper until smooth and creamy.
Quick Tip or Variation
Use a potato ricer for ultra-smooth texture. To reheat, microwave in a covered dish with a splash of milk to keep them soft and dreamy.
3. Brown Sugar Glazed Carrots
These glossy, candy-sweet carrots are the sleeper hit of any Thanksgiving table. They caramelize beautifully and hold up perfectly for make-ahead prep.
Ingredients
- 1 lb carrots, peeled and cut into sticks
- 1 tbsp olive oil
- 2 tbsp brown sugar
- 1/2 tsp salt
- 1/4 tsp black pepper
Instructions
- Preheat oven to 400°F and line a baking sheet with foil or parchment.
- Toss the carrots with olive oil, brown sugar, salt, and pepper.
- Spread evenly on the sheet and roast for 20–25 minutes, flipping halfway, until tender and caramelized.
Quick Tip or Variation
For extra depth, add a pinch of cinnamon or nutmeg before roasting. These reheat like a dream in the oven at 350°F for about 10 minutes.
Meal Prep & Storage Tips
Here’s how to stay a step ahead on the big day:
- Green Beans: Roast them the day before and reheat uncovered at 400°F for 5–7 minutes to crisp them back up.
- Mashed Potatoes: Store in a covered dish in the fridge. Reheat with a splash of milk and a pat of butter, stirring gently to restore that creamy texture.
- Carrots: Glazed carrots can be roasted ahead and rewarmed in the microwave or oven. They get even better after sitting in their glaze overnight.
Make It Your Own
- Dairy-Free Mashed Potatoes: Swap in unsweetened almond milk and vegan butter or olive oil.
- Maple Glazed Carrots: Sub brown sugar with pure maple syrup for a deeper sweetness.
- Spicy Green Beans: Add a pinch of red pepper flakes before roasting for a fiery twist.
- Boost the Aromatics: Add fresh thyme or rosemary to any of these sides for an earthy, holiday aroma.
