Savory Slow-Cooker Beef and Pear Roast

1 medium-sized beef roast (can be frozen)
1 white or yellow onion, sliced thick
5 carrots, peeled and sliced into large chunks
4 stalks of celery, sliced into large chunks
2 cloves of garlic, crushed or pressed (whichever is easier for you)
3 potatoes, cut into bite-sized pieces, skins on
4 pears, cored and sliced thick; leave the skins on
1 cup water
2-3 sprigs of fresh Rosemary (can use dried, just use about 2 teaspoons, or whatever looks good)
1 teaspoon dried, ground Thyme
1 teaspoon salt
1/2 teaspoon pepper

Place all into slow-cooker and turn on high for five hours. Switch to low for the next 4 hours. Remember, the meat can be frozen when you put it into the cooker; it will come out very tender, moist, and juicy. This dish makes it's own sauce while cooking and makes your home smell delicious! Serve with french bread or baguette, a fresh, crispy salad, and enjoy!
