The time depends on what the “1” refers to (pound, inch, etc.) and what you are cooking (chicken, steak, roast), so more detail is needed to be precise. As a rough example, boneless chicken breasts that total about 1 pound typically bake for about 18–25 minutes at 400°F/200°C until they reach an internal temperature of 165°F/74°C, while a 1-inch-thick steak usually cooks in about 8–10 minutes over medium‑high heat (pan or grill) to reach medium doneness, depending on temperature and flipping schedule.

Clarify the food

Please share:

• What ingredient you are cooking (for example, chicken breast, steak, pork chop, potato).
• Whether “1” means 1 pound, 1 kilogram, 1 inch thick, or something else.
• Your cooking method (oven, pan, grill, air fryer) and target doneness (for example, medium, fully cooked).

With that, a specific time and temperature range can be given, plus a safe internal temperature target for a meat thermometer.
