Slow-Cooked Sirloin

My family of five likes to eat beef, so this recipe is a favorite. I usually serve it with homemade bread or rolls to soak up the tasty gravy. —Vicki Tormaschy, Dickinson, North Dakota

    Mine wasn't bland at all and worked out really well for a busy day. I replaced the Green Pepper with 16 oz of sliced baby bella mushrooms, added 1/8C of Balsamic Vinegar, and 1/8 cup of Soy Sauce. I seasoned the steak with salt and pepper before browning it. Everything else I kept the same. I doubled the cornstarch slurry to make it as thick as I wanted it to be. It turned out great. The meat was surprisingly tender, which I was worried that it would be tough. I served it with mashed potatoes, green beans, and biscuits.

    This was a relatively simple meal and it was pretty good. I used stew meat and seasoned it a little bit while browning. I was diagnosed with gestational diabetes so it is hard to find things to eat. I have basically lived on peanut butter toast, grilled cheese and eggs. I needed a change and since hubby works out of town this will make me supper for a whole week. I paired it with some mashed potatoes and corn. I haven't checked my blood sugar yet after having this so we will see. This will be my rating for taste and ease of prep. I will rate again in about two hours after I test my blood sugar.

    This was horribly bland, even after I added cumin, garlic and smoked paprika. Wrong type of meat for a crockpot recipe.

    This was a waste of a good sirloin steak. It is more suited to a tougher cut of meat. Cooking on high for 3-4 hours was too much. I cooked it on high for 1 hour and then turned the heat down low for another 2 hours. The onions and peppers were mush and I didn't care for the strong taste of Worcestershire sauce. Nothing special at all.

    If you are looking for a comforting delicious slow-cooked recipe, this is it! It was delicious served with mashed potatoes. Next time I will serve is all over thick slices of bread.
