This Slow Cooker Pot Roast has such incredible flavor and the best gravy! Creamy potatoes, tender carrots, fall apart roast beef -- it's pure comfort food!
In a small bowl, combine the seasoning salt, garlic powder, Italian seasoning, onion powder, and pepper. Rub the mixture over the roast completely.
Heat a large skillet over high heat and add the oil. Sear the roast on all sides, just until browned. Place the roast into a 4- to 6-quart slow cooker.
Add the onion to the skillet and cook over medium heat, until softened. Add the broth, vinegar, tomato paste, Worcestershire sauce, and honey.
In a small bowl, whisk together cornstarch and water and add it to the skillet. Cook and stir over medium heat, scraping any bits off the bottom of the pan, for 2 to 3 minutes or until slightly thickened.
Place the potatoes and carrots around the roast in the slow cooker and pour the sauce over top. Cover the slow cooker and cook on low for 8 hours, until the roast shreds easily and the potatoes are tender.
Remove the roast and slice or shred.
Stir the ketchup into the gravy if desired. Serve the roast and vegetables with the juices.

Notes
*Be sure not to cut your potatoes or carrots too large or too small -- you don't want them to turn to mush during the long cook time but you also don't want them rock hard.
