If you’re a fan of comfort food mashups, the Meatball Sub Bubble Up Recipe is about to earn a permanent spot in your dinner rotation.

This recipe is pure crowd-pleasing magic that’s weeknight friendly but impressive enough to serve at any casual get-together.

Ingredients You’ll Need
There’s beauty in the simplicity of the Meatball Sub Bubble Up Recipe. Each ingredient plays a key role in building that crave-worthy balance of flavors and textures, from pillowy biscuits to gooey cheese. Here’s what you’ll need:
- Canned biscuits: These create the soft, chewy base and “bubble up” to form the delicious bread element of the casserole.
- Frozen meatballs: A major time saver that brings meaty, savory goodness to every bite; use your favorite variety for personalized flavor.
- Spaghetti sauce: Adds the necessary saucy tang and keeps everything moist — choose a robust, garlicky sauce if you love extra punch.
- Mozzarella cheese: Classic, stringy cheese pull is a must and adds that extra gooeyness we all crave.
- Provolone cheese slices: Layered on top for an irresistible golden, melty finish with just a hint of sharpness.
- Cooking spray: To ensure the casserole releases beautifully from the dish without any sticking.
How to Make Meatball Sub Bubble Up Recipe
Step 1: Prep the Dish and Oven
Start by grabbing your trusty 13 x 9-inch baking dish and giving it a quick spritz with cooking spray. This step might seem small, but it ensures the cheesy bits don’t glue themselves to the pan. While you’re at it, preheat your oven to 375 degrees F so everything is ready to bubble up in perfect harmony.
Step 2: Cut the Biscuits
Open your can of biscuits and separate all 10. Using kitchen shears (or a sharp knife), snip each biscuit into six pieces. These little dough nuggets are what create those irresistible, pillowy “bubbles” in the Meatball Sub Bubble Up Recipe. Don’t stress over getting them perfectly even — rustic charm is part of the fun!
Step 3: Coat Biscuits in Sauce
Tumble the biscuit pieces into your prepared baking dish. Pour on the spaghetti sauce and stir until each biscuit is well coated. This is where the magic starts — as the biscuits bake, they’ll soak up that sauce, turning every bite into a saucy, flavorful delight.
Step 4: Add the Meatballs
Scatter your frozen meatballs across the top of the saucy biscuits, tucking them in so they settle into the doughy base. Make sure each portion will get plenty of meatball action — it is, after all, a Meatball Sub Bubble Up Recipe, and every forkful deserves that classic filling.
Step 5: Add the Cheese Layers
Time for the best part: cheese! Sprinkle mozzarella generously over the whole dish, followed by a layer of provolone slices. The mozzarella melts into a gooey stratum, while the provolone gives a golden cap that mimics a warm, toasty sandwich finish.
Step 6: Bake Until Bubbly
Slide your casserole into the preheated oven and bake for 30 to 40 minutes, or until everything is hot, bubbly, and the cheese is beautifully golden. The Meatball Sub Bubble Up Recipe is done when the biscuits have puffed up and there are delicious caramelized edges. Let it cool for just a few minutes before serving so you don’t miss out on the perfect cheese stretch.
How to Serve Meatball Sub Bubble Up Recipe

Garnishes
For a restaurant-worthy finish, sprinkle chopped fresh parsley or basil over the top right before serving. A dusting of grated Parmesan is also a pro move and adds a little extra savory kick to your Meatball Sub Bubble Up Recipe. For those who adore spice, a dash of crushed red pepper flakes is perfection.
Side Dishes
This casserole is hearty, so pair it with something light and crisp, like a simple green salad tossed in a zesty Italian vinaigrette. Garlic bread is always welcome at the table (because let’s be honest, there’s never too much bread), or you can brighten things up with roasted veggies. The dish’s Italian-American roots make it super versatile with almost any classic sides.
Creative Ways to Present
To really impress, scoop generous portions into individual bowls and top with extra sauce and cheese. For a playful party twist, serve the Meatball Sub Bubble Up Recipe in muffin tins for personal, hand-held servings. Or, create a build-your-own sandwich bar with toasted hoagie rolls, letting guests pile casserole portions onto buns for the ultimate meatball sub experience.
Make Ahead and Storage
Storing Leftovers
Leftovers of the Meatball Sub Bubble Up Recipe are actually something to look forward to. Allow the casserole to cool completely, then cover the dish tightly with foil or transfer portions to airtight containers. Store in the refrigerator for up to 3 days, and the flavors somehow get even better overnight.
Freezing
If you’re planning ahead or want to stash some away for a busy week, freezing works wonderfully. Wrap the unbaked or baked (and cooled) casserole tightly in a double layer of foil. It should keep well for up to 2 months. Thaw overnight in the fridge before reheating for best results.
Reheating
To reheat, cover the casserole with foil and bake in a 350-degree F oven until warmed through and the cheese is melty, about 20-25 minutes. For single servings, a quick zap in the microwave will do, but you’ll get the best texture by reheating in the oven so those biscuit bubbles stay fluffy and not soggy.
FAQs
Can I use homemade meatballs instead of frozen?
Absolutely! If you have homemade meatballs on hand, use them for an extra-special touch. Just make sure they’re fully cooked before assembling the Meatball Sub Bubble Up Recipe to keep your prep simple and the bake time consistent.
What type of biscuits work best?
Regular canned buttermilk biscuits are ideal, but you can use flaky or homestyle varieties, too. Just steer clear of the extra-large “Grands” biscuits, as they might not cook through as evenly in the casserole.
How can I make this Meatball Sub Bubble Up Recipe vegetarian?
Swap out regular meatballs for your favorite store-bought vegetarian or plant-based option. There are plenty of tasty choices, so you can easily customize this recipe for all preferences without losing that comforting, saucy, cheesy vibe.
Is it possible to assemble ahead of time?
Yes! You can assemble the Meatball Sub Bubble Up Recipe up to the point of baking, cover tightly, and refrigerate for up to 8 hours in advance. Add a few extra minutes to the baking time if starting from cold.
What should I do if the biscuits seem doughy after baking?
If you find the center is still a bit underdone, simply cover the casserole loosely with foil and bake for an additional 5-10 minutes. This traps the heat, allowing the biscuits to finish cooking without over-browning the cheese.
Final Thoughts
Whether you’re feeding a hungry family, hosting friends, or just craving the ultimate comfort food, the Meatball Sub Bubble Up Recipe is pure happiness in a casserole dish. Give it a try for your next weeknight dinner or casual gathering — I guarantee it’ll earn fans and requests for seconds!
