- Season the Top Round Roast with salt and pepper on all sides. Heat a large skillet over medium-high heat. Add a bit of oil to the pan. Sear the Roast on all sides until it forms a golden brown crust. Place the seared Roast at the bottom of the slow cooker.
- Add the sliced onions to the skillet. Cook and stir the onions for 3-4 minutes over medium-high heat to lightly brown them. They do not have to be fully cooked, just seared. Spread the thinly sliced red onions and minced garlic over the roast.
- In a bowl, mix together soy sauce, tomato paste, beef broth and French Onion soup mix.
- Pour this mixture over the Roast and onions. Cover the slow cooker and set it to cook on low for 6-8 hours or until the meat is tender and easily shreds.
- Once the roast is tender, carefully remove it from the slow cooker and place it on a serving dish. Sprinkle chopped fresh parsley over the top.
- Serve the Slow Cooker Fresh Onion Roast with your favorite sides like mashed potatoes or crunchy bread!
