I have made stuffing for years with EV Olive oil, enough only to soften onions & celery. Then I transferred the hot vegetables into a big bowl containing the dried bread crumbs. To this I would add chicken broth to my liking & poultry seasoning, salt & pepper to taste. Everyone has always loved it. I would be concerned that the addition of extra oil might give it a more greasy feel/ taste whereas the chicken broth, in my experience added nice flavor. Sorry I don’t have amounts, I just go by instinct. If in doubt, use less bc you can always add more. P.S., these are the only ingredients I have ever used in my stuffing. This recipe caught my eye bc of ‘Keto’ & so I will be trying my stuffing this year with possibly this bread recipe. This is how I found you & your question. Hope this helps.

Marcy,
Anytime you see butter, ask is it for flavor or frying? I would probably use an olive oil for stuffing. That’s what my aunt did. She hated butter. You don’t need a lot just enough to sauté the vegetables. Coconut oil adds coconut flavor unless you use the refined (my preference). That or avocado oil are great substitutes for frying.
