Keto One Pan Roasted Beef Tri-Tip
A straightforward one-pan dinner that delivers tender, medium-rare beef tri-tip alongside caramelized Brussels sprouts with crispy edges. The tri-tip is seasoned simply with salt, pepper, and garlic, then roasted at high heat with vegetables arranged around it. This version emphasizes the meat's natural flavor while the sprouts cook in the pan's dry heat and fat renderings, creating contrast in texture. Ideal for weeknight dinners or weekend gatherings when you want impressive results with minimal cleanup. The resting period ensures juicy slices.

Tips
Insert the meat thermometer into the thickest part of the roast, not resting in fat, for accurate doneness readings. Temperature continues rising about 10°F after removal, so pull at 135°F for medium-rare.
Arrange Brussels sprouts around (not under) the roast so they develop crispy, caramelized edges from direct oven heat and rendered fat.
Good to Know
Refrigerate leftover roast and vegetables in airtight container up to 4 days. Reheat gently in 325°F oven until warm.
Trim and quarter Brussels sprouts up to 1 day ahead. Prepare seasoning mixture and store in small container.
Slice roast against the grain. Serve with roasted Brussels sprouts and pan juices. Pairs well with crusty bread or mashed potatoes.
Common Mistakes
Do not cover the pan or add water to avoid steaming the meat and preventing browning.
Do not place thermometer in fat; it will register falsely high temperatures.
Do not skip the resting period; cutting immediately releases juices and dries the meat.

FAQ
Can I use a different beef cut?
Yes. Chuck roast or brisket work well but may require 10-15 extra minutes cooking. Avoid tender cuts like ribeye, which are better for quick searing. Adjust timing by 5-minute increments and check internal temperature.
What if my oven runs hot or cold?
Rely on the meat thermometer, not time alone. Check temperature starting at 35 minutes. If oven runs 25°F hot, reduce temperature to 400°F. If cold, increase to 450°F and add 5-10 minutes.
How long can I keep leftovers?
Refrigerate sliced roast and vegetables in airtight container up to 4 days. Freeze up to 3 months wrapped tightly. Thaw overnight in fridge before reheating at 325°F until warmed through.
