Slow cooked sausage sandwiches with peppers and onions

The best slow cooked sausage sandwiches are juicy, a little chewy, and have tasty toppings. They’re served on thick hoagie style rolls. And they keep hungry friends and family coming back for seconds. This slow cooked sausage peppers and onions recipe is an easy way to make sausage sandwiches. It’s one of my go-to slow cooker recipes for a crowd.

Slow cooking sausages with beer

This slow cooker sausage sandwich recipe is made with beer and has no sauce added. The slow cooked sausage marinated in beer creates tender, juicy sausages. The beer adds a ton of flavor to caramelized peppers and onions. Another option, instead of beer, is to slow cook the sausages in cider.

Browning sausages for the crock pot

As with any crock pot meat recipe, for best results, brown the sausages with olive oil in a medium-hot skillet. Before adding them to the skillet, poke holes in the raw sausages to help release steam. 

Searing sausages locks in a ton of flavor and gives them a nice crunch in the hoagie roll. Once the sausages are browned on the stove, add them to the crock pot with 1 inch of beer (about 1 cup).

Prepping the onions and peppers

Diced onions and peppers can go directly into the slow cooker. In my house, we LOVE caramelized onions (like these red wine caramelized red onions), so we sauté them on the stove first.

If you haven’t seen it yet, I have a trick to cutting the peppers. Or, should I say, my husband has a trick I stole and put on the internet. See how to cut bell peppers into strips.

Toppings for slow cooked sausage sandwiches

• Sauerkraut – tasty with german sausage or other pork sausages
• Marinara sauce or tomato sauce – great for pairing with a sweet Italian sausage or mild Italian sausage
• Bleu cheese crumbles

Leftover sausage meal ideas

Slow cooked sausages made in large quantities can feed a family for days. Add leftover sausages to homemade pizza, sausage rolls (made in puff pastry), pasta dishes or enjoy them for breakfast in a scramble with eggs.

Let me go on a little rant about the crock pot…

And my love/hate relationship with it.

Working from home makes throwing easy dinners in the crockpot together much more convenient. Back in my office days, cooking for 1 in my 20s, I used to try making crock pot meals so dinner would be ready without hassle.

But tossing food in the crockpot at 7am before heading to work, and not getting home until 6 or later, meant the food was cooking too long, and usually it got dry.

But crock pot meals have made a comeback in my house since starting to WFH. I can take a lunch break and toss all the ingredients in the slow cooker around 12pm. And it’s done by 5 or 6.

My favorite crock pot meals include spare ribs, whole chickens, Hawaiian style meatballs, and these sausage sandwiches – they’re all good options. Especially for National Hoagie Day (a May food holiday).

Cheers and sausages soaked in beers,
