Do you think onions and mushroom taste better if they're sauteed in olive oil or butter?

Butter. I would be happy either way but if you have both I would go with butter.

And a bit of garlic

Go for olive oil if you want a lighter dish and butter if you want something heavier. My wife and I use olive oil (and garlic salt), but both are good.

It really depends on the end use. olive oil if preparing for a sauce or adding to a dish; butter if they are being prepared as a feature of the sish.

I like mushrooms sautéed in butter on top of a steak; sautéed in olive oil for adding to a spaghetti sauce.

The mushrooms sautéed in Fleischmann’s Margarine. It has to be that brand. If I don’t have that available I’d use a little butter and a little oil combined.

The onions are fine in the margarine too, but I prefer onions in oil if cooked separately from the mushrooms. If I was going to eat them on steak or pork I would fry them in the leftover fat and oil from cooking the steak in the pan. I’d add a little water to loosen what’s in the pan and then add the onions.

I rarely cook with butter. If I want a butter taste I usually use half the amount and add oil if more fat is needed for the dish. You don’t need a lot of butter for a dish to take on the butter taste.

Butter.

I agree with @zenvelo on this.

Olive oil and it’s healthier.

@JLeslie I haven’t used margarine for years and years and years, only real butter. I miss the tubs, though. They were SO handy.

Thanks all.

I never buy the tub margarine. It’s probably healthier in the tubs though. I just use it for some very specific things. Sautéed mushrooms happens to be one of them. Sometimes I make mushrooms with zero fat. I just cook them right in sauce, or cook them in a shallow amount of salt water. The sautéed or more delicious though. I use very little butter and margarine. It takes me months to go through 4 sticks of either, unless I’m baking cookies and cakes for special occasions.

I started buying butter when I got food stamps. I could afford it then! And now I’m spoiled. It has to be real butter.

My cholesterol goes up when I look at butter. Not that I’m saying margarine is good for you. I try to cook with very little fat.

My doctor said he’s never seen cholesterol numbers as good as mine, so I don’t need to worry about it.

I’m so jealous of that. :)

Yes, I am fortunate. But I have shitty blood pressure.

I’m having both problems now. The blood pressure is a pain in the neck.
