Ham and Swiss Po’ Boy

I’m slowly (but surely) perfecting my homemade po’ boy bread. It has the perfect thin, but crunchy, crust, with a warm, soft inside. I just need to work on my dough rolling skills. Even still, that lack of loaf perfection doesn’t stop me from enjoying an absolutely great ham and Swiss po’ boy. The ham has a nice little spicy kick, the cheese just starts to melt. All topped with crunchy fresh lettuce mixed with spicy Creole mustard and fresh chopped tomatoes.

Ham and Swiss Po' Boy

The Right Chips For A Great Sandwich

I always grab a bag (or two) of Zapp’s chips to go with my ham and Swiss po’ boy. They have the best crunch and flavor, plus it’s a tradition to eat Zapp’s with a po’ boy. The last time (sadly, a long time ago) I was in New Orleans I had Zapp’s with my po’ boys, so I do the same at home. Food memories like that are the best, you know?

I almost always use Blue Plate mayonnaise in the dishes I make. I think it is the best around. If you can’t find it locally you can pick it up online for a fair price.

Crab Cake Po’ Boy

Oh how I do love po’ boys. Guaranteed great bread, with a crunchy crust and soft insides. Fresh toppings that always pack a little kick. And a bag of Zapp’s chips. The perfect meal. This crab cake po’ boy more than hit the spot. Tender, flaky crab cakes on a homemade po’ boy roll, topped with a killer spicy lettuce mix.

Crab Cake Po' Boy

Oh, The Creamy Lettuce Mix!

The lettuce mixture on this crab cake po’ boy has become my standard po’ boy dressing. It has just the right amount of kick for me, and a little crunch. I pick up a head of iceberg lettuce, shred and chop it, and stuff it into a baggie in the fridge, always on hand when I need to make a po’ boy, which is quite often.

I made the bread myself, using a dough recipe that uses a bread machine. The bread is perfect in flavor and texture. But I admit, my dough rolling technique needs work. Sometimes I get perfect loaves, sometimes I don’t. I could substitute French bread,  but honestly it’s not quite the same texture. Close, but not quite. Close enough in a pinch, I’d say.

I almost always use Blue Plate mayonnaise in the dishes I make. I think it is the best around. If you can’t find it locally you can pick it up online for a fair price.

Po Boy Bread from the Bread Machine

This is my go-to po boy bread dough recipe from the bread machine. No way am I enough of a baker to make a dough from scratch without a bread machine. I could never make something as good as this dough. It makes for the perfect po boy. The bread gets a nice crunchy, but thin, exterior. The insides are light, soft and airy.

I’ve made this po boy bread from a bread machine at least 30 times and every time it has come out great. Well, or it did after I got the hang of rolling it into a nice loaf shape. I also learned that cutting the slits isn’t just for making it pretty, the bread seems to keep a better shape.

Po Boy Bread from the Bread Machine

Those Pretty Slits

To get the slits just right you need to use a very, very sharp knife. You don’t want to manhandle the dough cutting it. You want the knife to go through it effortlessly.

Check out The Southern Po’ Boy Cookbook for ideas on how to use your po boy bread. I love making the ham and Swiss po boy from the cookbook, among others! (And you have to use this bread when making my Cajun Muffaletta poboys!)

Ingredients

For the glaze

  • 1 egg white
  • 1 teaspoon water

Instructions

  • Place ingredients into your bread machine in the order listed.
  • Process on the dough settings. After 5-10 minutes check the consistency of the dough. It should be sticky but not stick to the sides. If it is too dry add water, but in 1/2 teaspoon increments. If it is too wet add more flour 1 teaspoon at at time.
  • When the dough cycle is completed remove the dough to a lightly floured surface.
  • Roll the dough out into a rectangle that is approximately 16″ wide and 12″ deep.
  • Roll up the dough along the long edge.
  • Pinch the seam and ends closed and place onto a lightly greased baking sheet, seam-side down.
  • Cover with a cheesecloth and place into a warm place to rise until doubled, about an hour.
  • After about 30 minutes of rising preheat your oven to 425 F.
  • Uncover the bread and, using a very sharp knife, make a few 1/2″ deep slits along the top of the dough, about 2″ apart.
  • Whisk together the glaze ingredients and brush over the top of the dough.
  • Bake for 20 minutes.
  • Reduce the temperature to 350 F and bake another 5-10 minutes or until golden brown.
  • Let cool slightly before slicing.

Andouille Po Boy Version 2.0

I love a nice, big po boy sandwich. Even the most complicated po boy isn’t complicated, like this andouille po boy. In minutes I’m having a great meal. I do go through the ‘trouble’ of making my own po boy bread, but that’s mostly because I just cannot seem to find great po boy bread here. French bread will do in a bind, but it’s just not quite the same. The texture is definitely different. For a topping, I use a simple but wonderfully spicy lettuce mixture. And you can never, ever go wrong with andouille sausage. That perfect spicy kick, in a casing that pops when you bite into it.

Andouille Po Boy Version 2.0

A Crazy Good Sandwich

I use the lettuce mixture on all of my po boys, not just this andouille version. It’s also great on hamburgers or hot dogs. It takes only a minute or two to make. When I pick up heads of iceberg lettuce at the grocery store I’ll shred and chop them and place them into baggies or containers along with a paper towel. That way I always have lettuce on hand for a quick po boy.

I almost always use Blue Plate mayonnaise in the dishes I make. I think it is the best around. If you can’t find it locally you can pick it up online for a fair price.

Also try my more traditional andouille po boy served up with a classic comeback sauce.

Slow Cooker Beef Debris Po Boy

You make a po boy and I’ll eat it. You make a messy, dripping po boy and I’ll devour it. The messier, the better. It has to drip and run all over the place. That way I can dip my bread in the juices. Perfect. Like this slow cooker beef debris po boy. This is a sandwich of beauty and flavor and… messiness!

Slow Cooker Beef Debris Po Boy

Messy. Like It’s Supposed To Be.

‘Debris’ refers to beef that is cooked and then cut into shreds. In this case, we cut the beef first then cook it until it completely falls apart. The sauce is absolutely incredible. You’ll want to just take a spoonful of it and eat it right out of the slow cooker.

Patience. Tested.

The aroma of the beef cooking in the delicious sauce will drive you crazy all day long. You will find yourself doing like I did, trying to rush the clock forward to dinnertime. Fortunately this recipe for a slow cooker beef debris po boy makes a big batch so you’ll have plenty of it on hand to enjoy again and again.

I love sandwiches topped with tender slow-cooked beef. Try my Italian slow cooker beefspicy ItalianFrench dip and New Orleans roast beef sandwiches too.

Andouille Po Boy

I had an out-of-this-world good andouille po boy from Chef Dan’s Southern Comfort food truck the other day. And ever since, for darned near every minute of the day, I’ve been jonesin’ for another. This time I made my own. A good po boy requires a good remoulade. I made a big batch of Chez John’s Kaw-Cajun Comeback sauce, but any good remoulade will do. Just make sure it’s got some kick to it. The fantastic flavor of andouille and the remoulade are the stars of this sandwich. A little heat and a little spice. Perfect.

Andouille Po Boy

The Messier, The Better

The best po boy drips when you eat it. All down the front of your arms, on your shirt, and all over the table, and best, onto your plate so you can sop up the drippings with the last piece of bread from the sandwich. Those drippings have everything good in them, from remoulade to sausage juice. Good eats. I’m not sure that the drippings aren’t my favorite part. You’re guaranteed to get every flavor in one taste.

Also try my version 2.0 andouille po boy.

I love the taste of Andouille sausage. It’s not only great on a po boy, I like it in potatoes too.

Grilled Chicken Po Boy

The flavor from the marinade on this chicken is unbelievable. It makes for an absolutely awesome grilled chicken po boy, but the chicken would be just fine eaten by itself. Combine the tender, juicy flavorful chicken with some Kaw-Cajun Comeback sauce (or your favorite remoulade), fresh bread, lettuce, tomato and pickle and you have a sandwich you won’t soon forget.

Grilled Chicken Po Boy

Get Messy With it

I like to really load up on the remoulade sauce. The messier this grilled chicken po boy is, the better it is, is my motto. Plus, that remoulade sauce is fantastic. It has a nice kick to it. I always save that last little end bite of the bread for sopping up any juices that have accumulated on the plate. That’s the best bite of the entire dish right there. Everything in one big old delicious morsel!

If you’re not into messy go light on the remoulade. Or put some in a bowl on the side and dip the sandwich in it instead. Kinda like a French dip but oh so much better!

Also try my very messy grilled chicken and gravy sandwiches.

Smoked Pulled Pork Po Boy

One of my favorite things to throw on the smoker is a pork butt. Pulled pork is well worth the time it takes to make. I made a big batch of BBQ the other day. Now, usually, I’ll throw it on a bun with some BBQ sauce. Or I’ll even put it in a baked potato (soooo good!). This time, I went with a smoked pulled pork po boy.

Smoked Pulled Pork Po Boy

I Have To Have Slaw

You can pretty much throw anything on a smoked pulled pork po boy and it’ll be good, but start with good BBQ and you end up with a fantastic sandwich! And don’t forget the slaw. That coolness, that crunchiness, that’s what makes a good sandwich great. As does the messiness. A great sandwich makes a mess when you pick it up and take a bite. The juices have to run down your arm and onto your plate. Or into your lap. An ingredient here, an ingredient there will fall out onto your lap. You pick those up, get some of that juices from your plate on them, and into your mouth they go. Hey, I know it’s not pretty. It’s not supposed to me.

Kaw-Cajun Comeback Sauce

I put Kaw-Cajun Comeback sauce on just about anything. Po boys. Regular sandwiches (making them not just regular!). Wraps. Anything. Everything. I make a big squeeze bottle of this sauce and keep it on hand because it’s sooooo darned good and goes on darned near everything. I know I already said that but it’s true. It really does deserve to be used on everything.

Kaw-Cajun Comeback Sauce

One Winning Sauce

This recipe for Kaw-Cajun Comeback sauce comes from Chez John from Fat Johnny’s Front Porch. Do not omit the grated onion and garlic – they really make this sauce a keeper. If you cannot find Cajun Power Sauces where you are you can order them online. Although you can substitute other sauces, this sauce is best made with Cajun Power. It’s also fantastic on chicken wings.

Roasted Shrimp Po Boy

Roasting shrimp is a great way to bring out their flavor. And it’s really easy, too. Roast them and make a roasted shrimp po boy and you’ve got something really great! I used Chez John’s Kaw-Cajun Comeback sauce on my roasted shrimp po boy. You can also use your favorite remoulade, such as our spicy version. Of course, just a good ole mayonnaise works just fine too. Me, I prefer a spicy sauce on my po boys. And I do truly love po boys.

Roasted Shrimp Po Boy

Nothing Fancy. Just Deliciousness.

The star of the roasted shrimp po boy is of course the shrimp. So there’s no need to bury that great flavor with a lot of ingredients. This sandwich isn’t meant to be fancy. But it is ok if it’s a little messy. Sit down and enjoy, the shrimp are fantastic!
