I’ve made this Kirkland Pork Sirloin Tip Roast Recipe more times than I can count, and it never fails to impress.

It’s one of those recipes that tastes like it took hours of complex work, but it’s shockingly simple to prepare.

The herb and spice rub creates the most incredible crust, sealing in all the juices for a tender, flavorful roast every single time.

My whole family gets excited when they smell this cooking in the oven. It has become a staple in my home for both busy weeknights and special Sunday dinners.

Ingredients

This recipe relies on a powerful blend of common pantry spices to create a memorable flavor profile.

1.5 – 2 lb pork sirloin tip roast: A Kirkland roast is a great size for this, offering a good balance of meat to fat.
1 ¼ tablespoons smoked paprika: This gives the rub a deep, smoky flavor and a beautiful reddish color.
½ teaspoon cayenne pepper: Adds a subtle, warming kick. Feel free to adjust this based on your heat preference.
½ teaspoon freshly ground black pepper: Freshly ground pepper provides a more pungent and complex flavor than pre-ground.
1 teaspoon garlic powder: A classic choice that infuses the meat with a savory, aromatic base note.
½ teaspoon onion powder: This complements the garlic powder, adding a touch of sweetness and depth.
½ teaspoon dried oregano: Its earthy and slightly bitter notes pair wonderfully with pork.
½ teaspoon dried thyme: Adds a fragrant, slightly minty flavor that brightens the entire spice blend.
1-2 teaspoons kosher salt: I recommend starting with 1 teaspoon, as the saltiness can be adjusted to your preference. Kosher salt has larger crystals that distribute well.
2 tablespoons olive oil: This helps turn the spices into a paste, making it easier to apply and helping the crust to form.

Note: This recipe will provide 6-8 servings.

Variations

While the original recipe is fantastic, you can easily tweak it to suit your tastes or what you have on hand.

Spice Level: If you prefer a spicier roast, increase the cayenne pepper to a full teaspoon or add a pinch of red pepper flakes. For a milder version, you can omit the cayenne entirely.
Herb Swaps: Don’t have thyme or oregano? Feel free to substitute with other dried herbs like rosemary or marjoram. A poultry seasoning blend can also work in a pinch.
Different Rubs: Experiment with other flavor profiles. A mix of brown sugar, chili powder, and cumin can create a delicious sweet and smoky BBQ-style rub.
Citrus Zest: For a brighter flavor, add the zest of one lemon or orange to the spice and oil mixture. The citrus oils will add a fresh, zesty aroma that cuts through the richness of the pork.

How to Make Kirkland Pork Sirloin Tip Roast Recipe?

This recipe is wonderfully straightforward, with most of the time being hands-off while the oven does the work. The key is the flavorful spice paste that creates a perfect crust.

Prepare the Spice Rub

First, preheat your oven to 350°F. In a small bowl, combine the smoked paprika, cayenne pepper, black pepper, garlic powder, onion powder, dried oregano, dried thyme, and kosher salt. Pour in the olive oil and stir everything together until it forms a thick, paste-like consistency. Let this mixture sit for about 15 minutes to allow the flavors to meld and the paste to thicken.

Season the Pork Roast

While the rub is resting, prepare the pork. Rinse the sirloin tip roast under cool water and pat it completely dry with paper towels; this helps the spice rub adhere better. Place a wire rack on a foil-lined baking sheet. Generously coat the entire surface of the pork roast with the spice paste, using your hands to rub it into all sides and crevices.

Roast to Perfection

Place the seasoned roast on the wire rack. Cook for 60 to 90 minutes. The exact time will depend on whether the roast is straight from the fridge or closer to room temperature. Start checking the internal temperature with a meat thermometer after about 50 minutes. Pull the roast from the oven when it reaches an internal temperature of 142-145°F.

Rest and Serve

Transfer the roast to a cutting board and let it rest for at least 15 minutes before slicing. This is a critical step, as it allows the juices to redistribute throughout the meat, ensuring every slice is tender and moist. Slicing too early will cause the delicious juices to run out onto the cutting board. After resting, slice the roast against the grain and serve immediately.

Additional Tips for Making this Recipe Better

Over the years, I’ve picked up a few tricks that take this already great recipe to the next level.

I find that letting the pork sit on the counter for about 30 minutes before roasting helps it cook more evenly and reduces the total time in the oven. A cold roast takes significantly longer to cook through.
Don’t be shy with the spice rub! I make sure every inch of the pork is covered. This paste is what creates that flavorful, crispy crust that everyone loves.
My most important tip is to trust your meat thermometer, not just the clock. Ovens vary, and the shape of the roast matters. I pull my roast out when it hits 142°F, as the temperature will continue to rise by several degrees while it rests.
When I have extra time, I apply the rub to the pork several hours ahead of time and let it marinate in the fridge. This allows the flavors to penetrate the meat more deeply. Just remember to let it sit at room temperature for a bit before it goes into the oven.

How to Serve Kirkland Pork Sirloin Tip Roast Recipe?

This versatile roast pairs well with a wide variety of side dishes, making it suitable for any occasion. For a classic comfort meal, serve thick slices alongside garlic mashed potatoes and roasted green beans or asparagus. The savory juices from the pork are a perfect complement to the creamy potatoes.

For a lighter meal, consider serving the sliced pork over a bed of mixed greens with a simple vinaigrette. It also works beautifully with roasted root vegetables like carrots, parsnips, and sweet potatoes. For presentation, arrange the sliced pork on a platter and garnish with fresh sprigs of thyme or parsley to add a pop of color.

Make Ahead and Storage

This recipe is great for meal prep and stores exceptionally well, making it perfect for leftovers.

Storing

Allow the roast to cool completely before storing. Place leftover slices in an airtight container and refrigerate for up to 3-4 days. Keeping it in an airtight container prevents the meat from drying out and absorbing other odors from the fridge.

Freezing

This pork roast also freezes beautifully. You can freeze slices in a single layer on a baking sheet before transferring them to a freezer-safe bag, or simply place portioned amounts into bags. It will stay fresh in the freezer for up to three months.

Reheating

To reheat, you can gently warm slices in a skillet over medium-low heat with a splash of broth or water to keep them moist. Alternatively, place the slices in a baking dish, cover with foil, and heat in a 325°F oven until warmed through. Avoid the microwave if possible, as it can make the pork tough.
