Pioneer Woman Sirloin Tip Roast — honestly? It’s one of those old-school roasts that doesn’t look like much but hits hard. Juicy, herby, kinda cozy. The onion trick underneath? Yeah. Makes it all caramelized and soft. It’s easy, feeds a bunch, and makes killer leftovers for sandwiches or weird cold fridge snacks. You get it.
Jump to RecipeIngredients Needed
- 1 sirloin tip roast (4-5 pounds): lean, not fancy, but solid.
- 2 tablespoons olive oil: helps it crust up.
- 1 teaspoon garlic powder: easy flavour bomb.
- 1 teaspoon black pepper: fresh cracked if you care.
- Salt to taste: yeah you’ll wanna be generous here.
- 1 teaspoon dried rosemary: smells like your nan’s house at Christmas.
- 1 onion (thick rings): don’t separate ‘em. They’re your edible roasting rack.
How To Make Pioneer Woman Sirloin Tip Roast
Let the Meat Chill (Not Literally):
Take the roast outta the fridge. It needs 45 mins, maybe an hour, to lose that fridge chill. Cold roast + hot oven = no thanks.
Heat and Season:
Crank your oven to 450°F. While it’s preheating, rub your roast down with olive oil, garlic powder, black pepper, salt, rosemary. All sides. Don’t be shy.
Do the Onion Thing:
Slice the onion thick. Like chunky ringlet-thick. Don’t pull them apart. Lay them in your roasting pan — dark one’s best — and make a little bed. Meat sits on top.
Blast Then Chill:
Roast it at 450°F for 15 minutes. No peeking. Then drop the heat to 300°F and go for another 90 mins-ish. Start checking your thermometer after an hour, though.
Check Temp + Rest:
135°F = medium rare. 145°F = medium. Take it out a couple degrees early. Cover it with foil and let it nap for 20 minutes. Don’t skip this.
Slice and Eat:
Cut against the grain, thin as you can. Drizzle pan juices if you saved them. Toss the onions or eat ‘em if you’re weird (I do).

Recipe Tips
- A meat thermometer will save your soul.
- Always rest it. Always. It’s like nap time for meat.
- Dried herbs are fine. You don’t need fancy fresh rosemary.
- Don’t skip the onion trick. Trust me. It’s magic and weird and it works.
How to Store & Reheat
- Room Temperature: Don’t leave it out past 2 hours.
- Fridge: Slice or wrap tight. 3–4 days easy.
- Freezer: Wrap in foil + bag. Eat within 3 months.
- Reheat: Oven at 325°F is safest. Skillet’s great too. Microwaving? Meh. Do what you must.

FAQs
Is sirloin tip roast tender?

Can I skip the onions?
Technically yeah, but don’t. They stop the bottom from burning and add flavour.
How long does it take to cook?
About 1 hr 45 mins total. But use a thermometer. Times lie.

135°F. Pull it at 130°F and let it rest to hit it perfect.

Yep. Everything in this is naturally GF. Just check labels on spices.
