Step 6: Slow Cook the Roast

Cover the crockpot with the lid and cook:

Low Setting:

8–10 hours

High Setting:

4–6 hours

Cooking on low heat is recommended because it allows the meat fibers to slowly soften and become more tender.

The roast is ready when it reaches an internal temperature of approximately:

• 145°F (63°C) for medium doneness
• 190–200°F (88–93°C) for a more tender, pull-apart texture

For a traditional slow-cooked roast, the higher internal temperature creates the most tender result.

Step 7: Make the Homemade Gravy

After removing the roast and vegetables, strain the cooking liquid if desired.

Pour the liquid into a saucepan and bring it to a gentle simmer.

Mix:

• 1 tablespoon cornstarch
• 2 tablespoons cold water

Slowly whisk the mixture into the simmering broth. Cook for a few minutes until the gravy thickens.

Taste and adjust seasoning with salt and pepper.

Step 8: Rest and Slice the Roast

Allow the roast to rest for 10–15 minutes before slicing.

Resting allows the juices to redistribute throughout the meat, keeping every slice moist and flavorful.

Slice against the grain for the most tender pieces.

Tips for the Best Crockpot Sirloin Tip Roast

1. Do Not Skip Browning if You Have Time

Searing creates deeper flavor by developing a roasted crust on the outside of the beef.

2. Avoid Opening the Lid Frequently

Each time the lid is removed, heat escapes and increases cooking time.

3. Cook Low and Slow

The low setting gives the best texture because the meat has more time to soften.

4. Cut Vegetables into Large Pieces

Small pieces may become too soft after several hours of cooking.

5. Let the Meat Rest Before Cutting

This simple step helps preserve moisture and improves the texture.

Storage and Reheating

Store leftover roast in an airtight container in the refrigerator for up to 4 days.

To reheat:

• Warm slices gently in a saucepan with some leftover gravy or broth.
• Avoid overheating, as lean beef can become dry.

The roast can also be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating.
