What kind of roast is it? Chuck roast, I cook on the stove with seasonings and maybe oinons, adding potatoes. I browna bit, add in beef or chicken broth and once it comes to a boil, simer for a long time. That all depends on the size. For a boston roast type (big and round), I cook it in the oven. We are having one tomorrow actually. I think the one I have is about 1.5 or 2 pounds.
Combine 2 or 3 tablespoons olive oil
italian seasoning
salt and pepper to taste
onion powder if you have it
minced garlic or garlic powder
You can increase or eliminate whatever you want. If you like it a bit spicy, add some chili powder to the mix. You can also chop garlic and insert into the roast. Rub all over the roast, let sit for about an hour and then put in the oven at 350 for 30 minutes, lower the temp to 275 and cook for another 45 minutes or so. I use a meat thermometer to tell me when it is done so not sure about the exact timing. I have a small convection type oven so it is a bit closer to the heat source and comes out with a nice slightly crispy outside and so tender inside. My son who does not like beef very much absolutely loves this. I make mashed potatoes and veggies like green beans, snap peas or asparagus on the side.
