Why Youll Love It
This is one of those cozy recipes that tastes like childhood but feels even easier as an adult. You still get that sweet and tangy sloppy joe flavor, but instead of messy buns and drippy plates, it is all baked together in one dish.
Here is why it stays on repeat at my house:
It is a true one pan dinner once the meat sauce is done, the oven does the rest. It is crowd friendly because kids love it and adults do too. It stretches so a pound of ground beef can feed more people than you think. And if you are into casserole nights like I am, you can hop over to this casserole roundup for more weeknight ideas.
I also love that it is forgiving. If you are short on something, you can usually swap it with whatever is in the fridge and it still turns out comforting and tasty. 
How to Make Sloppy Joe Casserole
I am going to walk you through exactly how I do it, with simple steps and a couple little tips I have learned after making it way too many times. This version uses a biscuit style topping, but I will share other topping ideas in the variations section too.
What youll need
- 1 to 1.5 pounds ground beef (or ground turkey)
- 1 small onion, diced
- 1 bell pepper, diced (optional but I like it)
- 2 to 3 cloves garlic, minced
- 1 cup ketchup
- 2 tablespoons tomato paste (optional, for richer flavor)
- 2 tablespoons brown sugar (more or less to taste)
- 1 tablespoon Worcestershire sauce
- 1 teaspoon mustard (yellow or Dijon)
- Salt and pepper
- 1.5 to 2 cups shredded cheddar (or a cheddar blend)
- 1 can refrigerated biscuit dough or a tube of crescent dough
- Optional: a pinch of chili powder or smoked paprika

Step by step directions
1) Preheat your oven to 375 F. Lightly grease a 9×13 baking dish.
2) In a large skillet over medium heat, cook the ground beef with the onion and bell pepper. Break it up as it cooks. When the meat is no longer pink, drain off extra grease if there is a lot.
3) Add garlic and cook for about 30 seconds, just until it smells good.
4) Stir in ketchup, tomato paste, brown sugar, Worcestershire, mustard, salt, pepper, and any extra seasoning you like. Let it simmer for 5 to 8 minutes so it thickens a bit. If it looks too thick, add a splash of water.
5) Pour the sloppy joe mixture into your baking dish. Sprinkle the cheese on top.
6) Add the biscuit dough on top. I usually tear each biscuit into 2 to 3 pieces and scatter them evenly so every scoop gets some topping. If you use crescent dough, you can lay it across and pinch a few seams, no need to be perfect.
7) Bake 20 to 25 minutes, or until the biscuit topping is golden and cooked through. If the top browns too fast, loosely cover with foil for the last few minutes.
8) Let it sit for 5 to 10 minutes before scooping. This helps it set up and keeps it from sliding all over the plate.
Little detail that matters: simmering the sauce before baking keeps the casserole from turning watery. And letting it rest after baking makes it feel more like a real sliceable dinner instead of a sloppy scoop.
I made this for a game night and everyone went back for seconds. The biscuit topping was the best part, and it was way less messy than regular sloppy joes.

Make Ahead and Storage Tips
This is one of my favorite parts about SLOPPY JOE CASSEROLE. It is super practical. If you like to prep dinner earlier in the day, you can do most of the work before anyone even starts asking what is for dinner.
Make ahead: Cook the meat sauce, let it cool, and store it in the fridge up to 2 days. When you are ready, pour it into the baking dish, add cheese, add the biscuit topping, and bake.
Fridge storage: Leftovers keep well in an airtight container for 3 to 4 days. The topping softens a bit, but the flavor is still great.
Freezer tip: Freeze the meat sauce by itself for up to 3 months. I do not love freezing it with the biscuit topping because it can get a little weird in texture when reheated. Just thaw the sauce in the fridge overnight, then assemble fresh.
Reheating: Microwave works for quick lunches, but the oven is best if you want the topping to perk up again. Cover with foil and warm at 350 F until hot.

Substitutions and Variations
One reason I make SLOPPY JOE CASSEROLE so often is that it plays nice with whatever I have. Here are a few swaps I have tried, plus a couple I want to try soon.
Meat options: Ground turkey or ground chicken works. If you go lean, add a tiny splash of oil when cooking the onion so it does not dry out.
Sauce shortcuts: You can use a canned sloppy joe sauce if that is what you grew up with. I still like adding a spoon of mustard and a dash of Worcestershire to make it taste more homemade.
Veggie boosts: Finely chopped mushrooms, shredded carrots, or zucchini can disappear into the sauce if you need to stretch it.
Topping ideas: If you do not have biscuit dough, try:
Cornbread batter for a sweet cozy top, tater tots for crunch, or cooked pasta stirred into the filling for a more casserole noodle vibe.
Cheese swaps: Cheddar is classic, but pepper jack gives a little kick, and mozzarella makes it extra melty.
And if you are craving that old school comfort food feeling, this Amish country casserole is another one that hits the spot.
What to Serve with Sloppy Joe Casserole
This is hearty on its own, so I usually keep sides simple and fresh. The sweet and tangy filling loves something crisp next to it.
My go to sides are:
- Simple green salad with a quick vinaigrette
- Steamed green beans or broccoli with butter and salt
- Pickles or pickle spears for a little bite
- Oven roasted potatoes if you are feeding extra hungry people
- Fruit on the side for kids, like apple slices or grapes
If I am serving guests, I will put out hot sauce, extra shredded cheese, and a little bowl of diced onions. People like making their own plate feel special.
Common Questions
Can I make SLOPPY JOE CASSEROLE less sweet?
Yes. Cut the brown sugar in half, and add a little more mustard or a splash of vinegar to balance it out.
Do I have to use biscuit dough on top?
Nope. Crescent dough works, cornbread batter works, and tater tots are honestly really fun if you want a crunchier top.
How do I keep the bottom from getting watery?
Simmer the sauce for a few minutes before baking and do not skip the resting time after it comes out of the oven.
Can I make it spicy?
Totally. Add diced jalapenos, chili powder, or a spoon of hot sauce in the meat sauce. Pepper jack cheese on top helps too.
Is this good for leftovers?
Yes, it reheats nicely. It is one of those lunches that makes you happy at your desk because it actually feels like real food.
