📖 Recipe
Garlic Bread Casserole
Print Pin Recipe Rate RecipeIngredients
- 1 baguette, sliced thickly - you may need 2
- ½ cup garlic butter, you may need more, use prepared from the store or homemade (recipe is on restless chipotle)
- 1 ½ pounds lean ground beef
- 24 ounces marinara sauce
- 2 cups Mozzarella cheese, shredded from a block or use Kraft creamy melt.
Instructions
- Preheat the oven to 400F..
- Spray a 13x9 inch pan with no-stick cooking spray. Set aside.
- Spread the bread slices with garlic butter and bake at 400F for 10 to 15 minutes.
- Turn the oven down to 375F.
- Layer in the bottom of a 9x13 baking dish.
- Saute the ground beef in a skillet over medium high heat until completely browned.
- Add salt and pepper to taste and drain any excess grease.
- Stir the pasta sauce into the meat.
- Spread the meat and sauce mixture over the garlic bread.
- Sprinkle the mozzarella on top.
- Bake at 375F for 20-25 minutes, or until heated through.
Notes
- Feel free to use stale bread. Don't use anything that's gone rock-hard, but if your baguettes are getting a bit old, there's nothing like a delicious garlic butter mixture and layers of cheese to perk them back up!
- If your casserole dish is extra full, place it on a baking sheet before putting it in the oven. This will catch any tomato sauce that spills as the melty cheese bubbles up!

🔪 How to make garlic bread casserole
This easy garlic bread casserole comes together fast and doesn't require anything fancy -just a pan, a little layering, and the confidence of someone who knows cheese will fix most things. We're crisping the bread, building some saucy layers, and letting the oven do the heavy lifting. Don't overthink it-this is more "assemble and bake" than "measure and stress."

- Slather those baguette slices with garlic butter like you mean it. (Already using leftover garlic bread? Look at you, saving time and making good choices.)
- Put them into a *13x9-inch casserole dish and bake until they're toasty and smelling like you've got your life together.
- While that's happening, brown the ground beef and stir in the pasta sauce like the multitasking legend you are. Spread that saucy beef mixture all over the bread-no delicate placement, just get it on there.
- Pile on the mozzarella and bake until it's melted, bubbly, and starting to get those golden spots that make people hover near the oven.
*I love this casserole dish because it has its own cover for storing leftovers. If there are any. Which is unlikely.
😱 What can go wrong (and how to fix it)
Even an easy garlic bread casserole can go sideways if you rush it…
🥖 Bread too soft or soggy
You didn't toast it enough. That bread needs a little backbone before it hits the sauce or it'll just give up and collapse.
🥖 Dry, sad casserole
Not enough sauce. This is not the time to be conservative-give it something to soak up.
🥖 Greasy situation
Didn't drain the beef. We're making dinner, not an oil slick.
🥖 Cheese didn't melt right
Pre-shredded strikes again. It'll work, but freshly shredded melts smoother and acts right.
🥖 Burnt top, cold middle
Oven too hot or pan too crowded. If it's piled high, give it time-or cover it loosely with foil so it doesn't go rogue on top.

👩🍳 FAQs
My favorite garlic butter is made with Italian seasoning, parmesan cheese, and, of course, garlic and butter. It's a compound, or "fancy," butter spread that's great on bread, stirred into pasta, as a dipper for appetizers, and more!
Yep. Bake it first, then use it just like leftover garlic bread. No one will know, and more importantly-you won't care.
Yep. Assemble it, cover, and stash it in the fridge for up to a day. Bake when you're ready and pretend you planned ahead.

If you like dinners that come together fast and don't apologize for being a little extra, you've got options. Taco Crescent Roll Pizza is what happens when taco night and pizza night stop pretending they're separate events-flaky, cheesy, and done in about 25 minutes. And if you're in the mood for something rich and comforting, Million Dollar Spaghetti Casserole lives up to its name with layers of beefy, cheesy goodness that also happens to freeze like a dream.
Then there's Southern Chicken Spaghetti, the quiet overachiever of the group. Creamy, cozy, and somehow more satisfying than anything with red sauce has a right to be, it's the kind of dish that shows up, steals the spotlight, and doesn't explain itself.
These are the dinners you make when you want full plates, zero complaints, and maybe just a little bit of glory.
🍽️ Serve easy leftover garlic bread casserole with ...
If you want to round this out into a full, no-one-leaves-hungry situation, keep it simple but strategic. A bright, chilled tortellini pasta salad cuts through all that cheesy richness, maple roasted carrots bring a little sweet, caramelized balance, and buttermilk pound cake finishes things off like you absolutely meant to serve dessert all along. It's the kind of spread that makes dinner feel complete without making you work any harder than necessary.
Don't just stand there drooling - get this in the oven! It's almost dinner time!
