Crockpot Beef Tips and Gravy

1 1/2-2 lbs beef tips
1 1/2 T. lemon pepper seasoning , optional
1 envelope onion soup mix*
1 can cream of mushroom soup
14.5 oz can beef broth
2 T. butter
3 T. flour, I use Wondra flour because it blends better
sliced mushrooms, optional, (I use 8 oz. can, drained)

Line crockpot. Combine soup mix, soup, and broth. Sprinkle seasoning on beef tips, if using. Add meat to crockpot, and add soup mixture. Stir to coat. Cover and cook on low 6-8 hrs. Melt butter, add flour, and stir to combine. Remove 2 c. of broth from crockpot and add to pan. Stir until thickened. Add back to crockpot and stir well. Add sliced mushrooms, if using. Serve over rice, mashed potatoes, or egg noodles if desired.*I have also used beefy onion soup mix. This recipe can be doubled.

I like serving these tender tips over crockpot baked potatoes : ) Yum!
