Tender, flavorful, and perfect for Sunday dinner or holiday meals. This roast is a family favorite and naturally gluten-free.
Roast beef always feels a little special, doesn’t it? In the Gallagher house, it was the centerpiece of many cozy Sunday dinners. This top sirloin roast recipe is simple, classic, and naturally gluten-free—no flour, no gravy mixes, just real food done right.
Top sirloin is leaner than other roasts, but when cooked properly, it’s juicy, flavorful, and perfect for slicing. I love it served with my gluten-free mashed potatoes and a rich pan gravy (optional, but highly encouraged).
Why I Love This Recipe
No flour, no fuss: A naturally gluten-free dish with no weird swaps.
Great for a crowd: A 5–6 lb roast can serve 12–16 people.
Budget-friendly: Top sirloin is often more affordable than ribeye or tenderloin.
Make-ahead friendly: Leftovers are amazing.
Ingredients You'll Need
Top sirloin roast (5–6 lbs) – Choose one with a nice fat cap for moisture and flavor.
Garlic cloves (15!) – I tuck slivers all over for that classic flavor.
Salt, cracked pepper, thyme, oregano – A simple, flavorful rub that enhances the meat.
Cooking Tips
Bring roast to room temperature: Let it sit out for about 1 hour before roasting.
Use a thermometer: This is key for perfectly cooked beef!
Medium-rare: 135°F
Medium: 145°F
Let it rest: After cooking, tent loosely with foil and rest for 15–20 minutes before slicing.
Optional Gravy
I always make a gluten-free pan gravy using the drippings, a little beef broth, and cornstarch. Just whisk 1–2 tablespoons of cornstarch with cold broth or water, then stir into hot drippings and simmer until thick. Season to taste with salt and pepper.
Serving Suggestions
This roast is perfect with:
Simple peas (I just use a bag of frozen peas)
Roasted carrots or green beans
A side of warm gluten-free dinner rolls
