Creating Sheet Pan Steak and Potatoes is a straightforward endeavor. Follow these easy steps to achieve a delicious meal:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Prepare Marinade: In a small bowl, combine olive oil, minced garlic, rosemary, salt, black pepper, and paprika. Mix well to create a marinade.
3. Marinate the Steak: Place the flank steak in a shallow dish and pour half of the marinade over it. Let it marinate for at least 15 minutes at room temperature, or up to 2 hours in the refrigerator for deeper flavor.
4. Prepare the Potatoes: In a large bowl, toss the halved baby potatoes with the remaining marinade, ensuring they are well coated.
5. Arrange on Sheet Pan: On a large sheet pan, lay out the marinated potatoes in a single layer. Leave space for the steak in the center.
6. Add the Steak: Once the potatoes are ready, remove the steak from the marinade and place it in the middle of the sheet pan.
7. Bake: Place the sheet pan in the preheated oven and bake for about 20-25 minutes, or until the steak reaches your desired doneness and the potatoes are tender and golden brown.
8. Rest the Meat: Remove the pan from the oven and let the steak rest for about 10 minutes before slicing.
9. Slice and Serve: After resting, slice the steak against the grain and serve with the roasted potatoes on the side.
10. Garnish: Optionally, sprinkle the dish with fresh parsley for added flavor and presentation.

These simple steps will lead you to a hearty meal that everyone will love.
