How Long to Sous Vide a Sirloin Tip Roast: 3 Proven Time Ranges for Perfect Results

I still remember the first time I cooked a sirloin tip roast sous vide—it was a cool Sunday in Florida, and my local butcher had this beautiful 3.5-pound roast on sale. It wasn’t a premium cut, but I was determined to make it taste like one. That’s the magic of sous vide. You take something tough and transform it into something incredibly tender just by dialing in the right temperature and letting time work its magic.

That day, I cooked the roast for 24 hours at 131°F. When I sliced into it, the meat was rosy pink edge to edge—juicy, tender, and packed with flavor. My husband thought I’d spent a fortune at a steakhouse. Nope. Just sous vide and patience.

Ever since then, I’ve made this dish part of our monthly rotation, especially when we want something hearty and affordable. And let me tell you, getting the cooking time right is what makes or breaks this cut.

Why Time and Temperature Are Everything

The sirloin tip roast isn’t a naturally tender cut. It’s lean and can get chewy if rushed. But when cooked low and slow, it transforms. The key question—how long to sous vide a sirloin tip roast—depends on two main factors: the texture you want and the source of your meat.

Here’s a quick cheat sheet:

Texture	Time	Temperature
Medium-Rare, Tender	24–36 hours	131°F / 55°C
Medium, Sliced Thin	18–24 hours	136°F / 58°C
Fork-Tender	36–48 hours	138°F / 59°C

What’s so cool about sous vide is the flexibility it gives you. Once you know how long to sous vide a sirloin tip roast, you can start the cook before bed and forget about it until dinner the next day. The roast just gets more tender over time—no risk of overcooking, no dried-out meat, just consistent perfection.

I often come back to this exact guide whenever I’m deciding how long to sous vide a sirloin tip roast, especially when switching between cuts. Whether it’s grass-fed or conventional, knowing the time window makes the process stress-free.

Another bonus? Even tougher cuts like chuck or top round respond beautifully to this method. When I made this sous vide roast beef last month, I used the same seasoning and technique—but went with 36 hours in the water bath. The result? Melt-in-your-mouth, fall-apart tender.

Now that you’ve locked in how long to sous vide a sirloin tip roast, the next section walks you through the step-by-step: from seasoning and sealing to the final, flavorful sear. Get ready—this roast is about to steal the show at your dinner table.

The Perfect Sirloin Tip Roast, Step-by-Step

If you’re wondering how long to sous vide a sirloin tip roast and want an easy, repeatable method, this is the one I swear by. It works for both supermarket cuts and grass-fed roasts—and it never fails.

Here’s how I prep it:

Start with a 3 to 4-pound sirloin tip roast—a lean cut that really benefits from the slow, steady heat of sous vide. Because it’s naturally low in fat, building flavor from the outside in is key. Season the roast generously with salt, pepper, ½ tablespoon garlic powder, ½ tablespoon paprika, and ¼ tablespoon ancho chile powder. This smoky, earthy blend creates a deep, flavorful crust that complements the beef beautifully.

Add two sprigs each of thyme and rosemary directly into the sous vide bag. These herbs infuse subtle aromatics throughout the cook. Seal everything tightly—either with a vacuum sealer or using the water displacement method if you’re sealing by hand.

Now, let’s talk about how long to sous vide a sirloin tip roast, because this part makes all the difference:

• Grass-fed or leaner roasts: Cook at 131°F for 12–18 hours for a firmer, sliceable texture.
• Conventional or tougher supermarket cuts: Go for 24 to 48 hours at 131°F for a more tender, buttery finish.
• Prefer medium doneness? Bump the temp up to 136°F.
• Want fork-tender, fall-apart texture? Try 138°F to 140°F, but only if you’re after that shredded roast feel.

I usually go the full 24 hours, especially when using grocery store sirloin tips. I’ve even pushed it to 36 hours, and the result is always incredible—ultra-juicy and tender enough to cut with a fork.

Don’t Forget the Sides: Brussels, Tomatoes & Onions

While your roast is relaxing in its warm water bath, you’ve got plenty of time to build a meal around it. And trust me—these sides aren’t just afterthoughts. Once you’ve figured out how long to sous vide a sirloin tip roast, pairing it with the right accompaniments takes your dish from great to unforgettable.

Roasted Brussels Sprouts with Cherry Tomatoes
Preheat your oven to 400°F. Trim and halve 2 pounds of Brussels sprouts, then toss with olive oil, salt, pepper, and 4 cloves of minced garlic. Spread on a baking sheet and roast for 30–45 minutes, stirring occasionally.

In the last 5–10 minutes, add 1 pint of cherry tomatoes. When they begin to burst, you’ll have the perfect sweet-savory balance to match your sous vide roast.

Sautéed Onions with Garlic & White Wine Vinegar
While your sirloin is cooking (because yes, how long to sous vide a sirloin tip roast gives you time to multitask), heat olive oil in a skillet over medium heat. Add 3 sliced yellow onions and 2 minced garlic cloves. Cook low and slow—about 15 to 20 minutes—until golden and soft. Add 1 tablespoon of white wine vinegar to brighten it all up.

Bringing It All Together
Once the roast is done (whether you chose 24, 36, or even 48 hours based on how long to sous vide a sirloin tip roast), pat it dry and sear it in a hot cast iron pan for 1–2 minutes per side. This is your crust moment—don’t skip it.

To serve, top your veggies with a splash of fresh lemon juice and a sprinkle of thyme leaves. Slice the roast against the grain, layer it with those rich onions, and dig in.

Can You Overcook a Roast in Sous Vide?

This is one of the most common questions I get: “Can you overcook a roast in sous vide?” The short answer? Not really—but when it comes to learning how long to sous vide a sirloin tip roast, the long answer matters even more.

With traditional roasting, you’re racing against time to avoid drying out the meat. But sous vide changes the game completely. The water bath holds a precise temperature—say 131°F—so your roast never cooks past your target doneness, whether it’s in the bath for 12 hours or a full 48.

That said, understanding how long to sous vide a sirloin tip roast helps you balance doneness and texture. A 12-hour cook gives you a firmer, sliceable roast—ideal for sandwich-style cuts. A 48-hour cook produces a fall-apart, brisket-like texture. You’re not “overcooking” in terms of temperature, but you can go past your ideal texture window.

Want to go deeper? This article on overcooking sous vide steak dives into time vs. texture in detail.

My recommendation: if you’re aiming for medium-rare sirloin, cook it at 131°F for 24 to 36 hours. If you want something extra tender—almost like pulled beef—extend to 44 to 48 hours. Either way, when you know exactly how long to sous vide a sirloin tip roast, you unlock full control over flavor, texture, and tenderness.

When Is Sirloin Tip Roast “Done”?

Sous vide flips our traditional understanding of “doneness.” Instead of watching a thermometer rise during cooking, we set the water to our ideal temp, and the roast comes up to it and stays there.

Here’s a handy reference for doneness:

Level	Temperature (°F)	Appearance
Rare	125°F	Bright red, soft texture
Medium-Rare	131°F	Pink throughout, tender
Medium	136°F	Pale pink center, firm
Medium-Well	144°F	Barely pink, dense
Well-Done	150°F+	Brown throughout, very firm

Keep in mind that sirloin tip is lean—so lower temps help it stay juicy. That’s why 131°F is the sweet spot for most people. Want to go bolder? Try it with compound butters or sauces, like this balsamic-glazed steak.

Also, the longer you sous vide, the more collagen breaks down. So yes—meat does get more tender the longer you cook it, as long as the temp is low and steady.

The Final Step: Searing, Slicing, and Serving

After hours of gentle sous vide cooking, your roast is perfectly done from edge to center—but don’t skip the finish! Once you’ve nailed exactly how long to sous vide a sirloin tip roast, the final step is what transforms it from “good” to unforgettable. A hot, hard sear adds bold flavor and crisp texture, giving you that satisfying bite with every slice.

Here’s how to do it right:

1. Remove the roast from its sous vide pouch and pat it completely dry with paper towels. Moisture is the enemy of a good crust.
2. Heat a cast iron pan until it’s smoking hot. Don’t rush this part—temperature is key.
3. Add a neutral oil with a high smoke point, such as avocado or grapeseed oil.
4. Sear the roast for 1 to 2 minutes per side, including the ends, until a deep golden-brown crust forms.

Once seared, let the roast rest for 10 minutes. Then, slice it against the grain. This small detail makes a big difference, especially with lean cuts like sirloin. You’ve already cooked it perfectly by understanding how long to sous vide a sirloin tip roast—this last step ensures it’s also perfectly tender when served.

Plate it over those roasted Brussels sprouts and burst cherry tomatoes, then top with caramelized onions. A quick drizzle of lemon juice and a sprinkle of fresh thyme leaves bring the whole dish together.
