Howdy –

And then there’s THIS!! These Creamy Mashed Potatoes Supreme with French Fried Onions and Bacon might just be the KING of ALL covered-dish recipes!  I’ve yet to take this dish anywhere that it wasn’t a huge hit.  I think it’s because everybody adores creamy mashed potatoes, especially when you top them with crispy French fried onions, cooked bacon, and, of course, CHEESE.  Sprinkle a few scallions over that for a little color and you’ve yo-self a dinner time MASTERPIECE. Woot! Woot!

What Ingredients Will You Need to Make Creamy Mashed Potatoes Supreme with French Fried Onions and Bacon?

Yukon Gold Potatoes.  Okay, you can actually use ANY type of potatoes for this recipe.  I just like Yukon Gold potatoes because of their extra-fluffy texture once they are cooked and the fact that there’s NO PEELING necessary – a huge win in my book because it saves time.

Sour cream, cream cheese, beaten eggs, prepared horseradish, salt and pepper.  Here’s what gives your mashed potatoes their texture and flavor.  If you’re not familiar with grated, prepared horseradish, now’s the perfect time to level up.  You will typically find this ingredient in the refrigerated meat or cheese section of your grocer.

And whatever you do, don’t opt for the creamy horseradish that’s available in the condiment section of the grocer – this absolutely isn’t what you want to keep on hand for cooking.  Prepared horseradish is just horseradish root that’s been grated and is packed in a bit of vinegar; it’s got LOTS of flavor and gives ZEST to your recipes.  I keep some on hand at all times!

French fried onions, cheddar cheese, scallions and bacon.  These ingredients are what make your Creamy Mashed Potatoes Supreme so gorgeous and mouth-watering.

Easy Recipe Tips for Making Creamy Mashed Potatoes Supreme

I’m on a low-carb diet. Can I substitute cauliflower for the potatoes in this recipe?

Oh man! So glad you asked this question….YES!!!  It works great and sometimes I don’t even TELL my family that this is what I’ve done when I make this casserole.  It is truly delicious made either way.  You will need 4-5 heads of cauliflower to make a big, full 9 x 13 pan. Also, the texture is slightly different, but once you gain a taste, you’ll see that cauliflower instead of potatoes is a great variation.

Can I make Creamy Mashed Potatoes Supreme ahead of time?

Sure can and I love that about this recipe.  You can make it 2-3 days in advance and just store it in the fridge until it’s time to bake.  Keep in mind that if this casserole is super-chilled when you place it into the oven to bake, you may need to add a 10-15 minutes to the baking time to get it hot throughout.

Are French-fried onions the onions that you use for the topping when making green bean casserole? 

Yep, and sometimes these are found in various locations at the grocer…it can be a chore tracking them down! I try to stock up on these and keep an extra bag/container of them in my freezer just for this very reason.

Would this casserole be good baked and served in a cast iron skillet?

You can bake this casserole in just about any serving dish and a cast iron skillet would be superb. Since this makes a big pan of potato casserole, I’d opt for a 12″ cast iron skillet – such a great idea!

What should I make with leftover mashed potatoes?

    1. Hi Phyllis – I’m sorry that I’m just now seeing your question here. I’ve never made that potato casserole in a crockpot, but I don’t see any reason that it could be done. I hope you enjoyed the prime rib, as well.
      Sincerely,
      Chef Alli

    1. Hi Phyllis – So sorry I didn’t see your question here sooner – forgive me! The eggs act as a binder, and when combined with the dairy products, I do think they make the potatoes creamier! Hope you will try this recipe. If you do, please let me know what you think of it and also rate it here if you would!
