Fat Ronnie’s Deep Fried Fresh Mushrooms

Fat Ronnie’s Deep Fried Fresh Mushrooms are some of the best-fried mushrooms you will ever eat. Crispy and crunchy on the outside, and tender on the inside.

If you have never tried deep frying fresh mushrooms it is easier than you might imagine. In just minutes you can have deliciously fried mushrooms in no time at all. Fried mushrooms are perfect for parties, watching the game, or as a side when you are frying fish.

What types of mushrooms can you fry?

You can fry just about any fresh mushroom. For this recipe, we will use fresh button mushrooms. You could use cremini, AKA baby portobello mushrooms. I like to pick up my mushrooms at Costco, they are a good value there.

Snap off the stems, and brush off the mushrooms with a moist paper towel to clean the mushrooms. Don’t rinse off the mushrooms or use your sprayer on them, mushrooms are delicate, and you may damage them.

preparing seasoned flour

This recipe uses a dry-wet-dry method. First, you will prepare a simple seasoned flour. Then you will fill a bowl with the buttermilk. The web mushrooms will go back into the seasoned flour.

The secret this crispy batter is the combination of baking powder in the flour, and the use of buttermilk. The baking powder and the buttermilk give the batter a good crispness and make the perfect combination for frying.

Frying fresh mushrooms

Frying fresh mushrooms takes just a few moments. I love my T-Fal deep fryer. If you do not have a deep fryer, you can fill a large heavy-bottomed pot with vegetable oil. The oil will need to be about 4 inches deep.

Heat the oil to about 350 degrees. Add a few mushrooms in at a time, and gently stir the mushrooms from time to time as they cook. They will be done when they are golden in color.

Don’t let the crust get soggy!

Instead of draining fresh mushrooms on paper towels, I lay them on a baking rack that rests in a bar pan. The excess grease will drain, but the food won’t steam like it can on a paper towel.

About Fat Ronnie’s

Fat Ronnie’s was located in Topeka, Kansas in the 1970s. Fat Ronnie’s was known for delicious food. He was the first person to offer deep-fried mushrooms in Kansas. This restaurant was a favorite of my family when we lived in the area.

Ronnie served his deep-fried goodness in paper bags. The bags were always full, and everything they served was delicious. Fat Ronnie’s was the brainchild of Ronald Williams, sadly he isn’t around anymore, but you can still make food just as good as his!

    We are making your deep fried mushrooms tonite. The responses that I read brought tears to my eyes. Thank you for sharing. I worked in a school cafeteria for a lot of years and treasure recipes. Am not anyways near Topeka and never been there. We live in the Mississippi Gulf Coast area. Praise the Lord, we survived Katrina. God bless Copy Kat and Ronnie too

    So… I had some yummy steaks that I made tonight, saw a couple of packages of white mushrooms in the fridge as I grabbed the steaks, and decided to Google a yummy recipe for fried mushrooms to dip in a sour cream horseradish sauce. I found this recipe.

    Firstly, it was DEEEEEEEELISH.
    Secondly, reading Fat Ronnie’s wife’s and son’s and customer’s comments made me feel really good. I’ve never heard of the place- it sounds like one of those local treasures that lives on in town memory for years. Thank you for the recipe and thank you for sharing the feelings and memories that cooks are driven to create with their food.

    I’m going to try these tonight! I’m from the Topeka area, but never heard of Fat Ronnie’s – where were they located?
    Fat Ronnie’s is no longer in business 🙁 Stephanie

    • Teresa Williams

      The first location was 21st and Hwy 75 (he thinks).
      Second location was 21st and Gage.
      Last location was on 29th and California Ave.
      Ron is touched that people are making his recipes and enjoying them nearly 40 years later. Anyone who would like to contact Ron can do so at [email protected].

  9. Teresa

    This is “Fat Ronnie’s” wife and he is so thrilled to see his recipes up and alive on the web. His health is failing now (he has a multitude of health issues and has recently had his right leg amputated). He wishes that Fat Ronnie’s was still around or that we could open a “Fat Ronnie’s Jr” type of place – but only in his dreams.

    If I can get more recipes from him, I will send them. Most of them are just a “I used to do this…” type of thing.

    Anyone interested in reading about Ron can check out my blog. Most of it is about him.

    I am really sorry to hear that Ron is going through so much, his restaurant was one of my favorite memories when growing up. I know my family has always talked about going there and getting some of his tasty food. ~stephanie

  10. Fat Ronnie Jr.

    I’ll be sure to pass that along. Most of his recipes are resting safely in his head for now. He hasn’t even given them to his own son! The image you used for the mushrooms and for the Fried onions are pretty spot on. When we were talking about them, he made it a point to let me know that they *always* filled up a brown paper bag.

    • Stephanie

      For those who didn’t go to Fat Ronnie’s he served everything in paper bags, you would walk out of there with fresh steaming bags of fried goodies.

  11. Fat Ronnie Jr.

    Fat Ronnie’s was owned an operated by my father, Fat Ronnie Sr. It brings me a real sense of pride to know that his food was so well remembered that people still make it 35 years later.

      • Teresa Williams

        Stephanie, his memory is not good any more and he can only remember bits and pieces of things, but not enough to put anything together. 🙁

      • stephaniemanley

        If you ever want to share what he does remember, i’ll see what I can do to construct a recipe. I loved this place as a kid. I can remember my Mom stopping there before we went to the pool in the summer. Loved it.
