How to Make Rosemary Roasted Sweet Potatoes
1️⃣ Chop the sweet potatoes. Cut into bite-sized cubes for even roasting.

3️⃣ Roast at 400°F. Spread evenly on a baking sheet and bake for 30-35 minutes, flipping halfway through.
4️⃣ Serve & enjoy! Garnish with extra fresh rosemary and serve warm.
Tips for the Best Roasted Sweet Potatoes
✔ Cut evenly – Uniform pieces cook at the same rate.
✔ Don’t crowd the pan – Too many potatoes = steaming instead of crisping.
✔ Use fresh rosemary – The flavor is much stronger than dried.
✔ For extra crispiness – Roast at 425°F for more caramelization.
How to Store & Make Ahead
Make ahead: Prep the potatoes in advance and roast just before serving.
Fridge: Store in an airtight container for up to 4 days.
Reheat: Warm in the oven at 350°F for 10 minutes to keep them crispy.
