We make our Thanksgiving turkey in a kettle bar-b-que, so this is how I make my stuffing:
Cubed, dry bread (Toasted, or not.)
Olive Oil with Butter, or just one of them
Onions, finely diced
Celery, finely diced
Portobello Mushrooms (optional) de-gilled and cut fine
Salt
Pepper
Poultry Seasoning....I prefer Schilling
Chicken Broth, canned or homemade
In a pan, saute the onions, celery, and mushrooms...if using, in butter, olive oil, or part of each. Salt and pepper them as you cook.
Have the bread cubes in one or more large bowls, only half filled, so you can toss without spilling....or use a roasting pan.
Sprinkle the Poultry seasoning on the bread, being careful to spread it around, tossing the bread as you go.
When veggies are ready, divide them evenly into the bowls of bread cubes, pouring on the oil/butter, as well. Toss well, using a fork, or salad utensils.
Now pour broth slowly over all, stirring as you go, allowing the bread to take in the liquid. Keep going until it's as moist as you like it, mixing well, but gently. It won't be cooking as long as you are used to, so don't have pools of liquid in the bowl after the bread has soaked up what it's going to. I tend to err a little on the dry side, rather than making a soaking mess.
Taste and add more salt or poultry seasoning, if it needs it, or just doesn't taste enough like stuffing.
Put the stuffing into Pyrex dishes, and bake at 350 degrees until it's done to your specs.
Some people use a deep dish, but we like the top, so I use shallower dishes.
