6 -7 lbs turkey breast, thawed, if frozen
1⁄2 cup chopped onion
1⁄2 cup chopped celery
fresh coarse ground black pepper
1⁄2 cup chicken broth
turkey broth, from crock pot
2 (14 ounce) cans chicken broth
3 tablespoons flour
Place onion and celery in cavity of turkey breast.
Sprinkle turkey with salt and pepper and place in 5 to 6 quart slow cooker.
Pour broth over turkey, cover and cook on low for 7 to 8 hours.
Remove turkey to serving platter, cover with foil to keep warm while making gravy.
Place liquid in saucepan after straining out veggies, and add 1 to 2 cans chicken broth- depending on how much gravy you want to make.
In a covered jar, shake together the flour mixed with about 1/2 to 1 cup of water until smooth- or you can whisk it in a bowl.
When liquid comes to a boil, slowly stir in flour mixture, adding just enough to thicken it to your liking.
Cook until it bubbles and thickens, stirring often.
