One sirloin tip roast (or other roast of your preference)
2 beef bullion cubes dissolved in 2 cups water, or two cups regular beef broth
2 cloves garlic, crushed
1 TBSP red pepper flakes
1 TBSP paprika
salt and pepper to taste
2 TBSP Worcestershire sauce
1 cup sweet yellow onion, in chunks
1/4 cup milk
1/4 cup corn starch
Rub top, bottom, and sides of roast with crushed garlic, red pepper flakes, paprika, salt, and pepper. Pour broth into crock pot, place onion chunks in bottom of crock pot. Place seasoned roast into crock pot on top of onions. Sprinkle top of roast with Worcestershire. Cover and cook on LOW for 10 hours (that seems to be the perfect amount of time for a really moist roast).
If you’re making potatoes to go with the roast, you can peel and quarter them and add them into the crock pot with the onions (add about a half-cup to a cup more broth). My family doesn’t happen to like the taste when the potatoes cook with the meat, so I leave them out. The roast is also good served over rice.
After removing the roast and onions (and potatoes or other veggies, if you added them) from the crock pot, pour the broth into a large sauce pan. Heat over medium-high heat until boiling. Meanwhile, combine milk and corn starch until smooth. Gradually add mixture to boiling broth, stirring constantly. Broth will thicken into gravy very quickly.
