Soup Bars are what happens when a bubbling pot of creamy vegetable soup meets a buttery cracker crust and a blanket of sharp cheddar. They slice like lasagna, eat like a savory pie, and taste like the coziest bowl of soup you have ever had, only handheld.

The trick is thickening the soup filling just enough that it sets firm once baked, while staying silky and spoonable when warm. A quick 8-minute simmer with a cornstarch slurry does the job, and a 10-minute rest after baking locks the bars so they cut into clean squares.
This is a brilliant way to use leftover soup, stretch a rotisserie chicken, or feed a crowd at a potluck without hauling out bowls and spoons. Serve them warm with a green salad and watch a 9×13 pan disappear in minutes.
Why You'll Love This Recipe
About the Ingredients
2 cups (about 200g) buttery round crackers, finely crushed
Ritz-style crackers give the crust its rich, salty snap; panko plus 3 tablespoons melted butter works if you are out. Buy extra crackers, since crumbs compress more than you expect.
6 tablespoons (85g) unsalted butter, melted, divided
Melted butter binds the crumb crust and keeps it from turning sandy; salted butter works, just skip the added salt. Use 2 tablespoons for the pan and 4 for the crumb mixture.
1 cup (115g) shredded sharp cheddar, divided
Sharp cheddar melts into gooey ribbons and adds tang; Gruyere or smoked gouda are excellent swaps. Shred it yourself for a smoother melt than pre-shredded.
4 cups (about 960ml) creamy vegetable or chicken soup, homemade or canned
Use a thick, cream-based soup rather than a brothy one, or the bars will not set. Canned cream of mushroom or cream of chicken thinned with 1/4 cup milk is a reliable shortcut.
1 cup (140g) frozen mixed vegetables, thawed and patted dry
Thawed peas, carrots, and corn add texture and color; fresh diced carrots steamed for 4 minutes also work. Patting them dry keeps the filling from turning watery.
1 1/2 cups (210g) cooked chicken, shredded (optional)
Rotisserie chicken is the fastest route and adds protein; leave it out for a vegetarian version. Canned tuna, drained well, is a surprisingly good substitute.
1/4 cup (30g) cornstarch whisked with 1/4 cup (60ml) cold water
This slurry is what turns soupy filling into sliceable bars; arrowroot or potato starch works 1:1. Always whisk into cold water first so it does not clump.
1 teaspoon garlic powder
Garlic powder blends evenly into the filling; 2 minced fresh cloves sauteed for 1 minute are a fine upgrade. Onion powder can stand in if that is what you have.
1/2 teaspoon freshly ground black pepper
Fresh-cracked pepper blooms in the warm filling; white pepper gives a milder heat. Taste the filling before baking, since canned soup is already salty.
2 tablespoons chopped fresh parsley, for garnish
Parsley adds a fresh green finish; sliced scallions or torn basil also work. Add it after baking so it stays bright.
Tips & Tricks
Thicken Before Baking
Simmer the filling with the cornstarch slurry for a full 2 minutes until it visibly coats a spoon, or the bars will slump when sliced.
Press the Crust Firmly
Use the flat bottom of a measuring cup to pack the crumb mixture hard into the pan corners, which prevents a crumbly base.
Rest Before Slicing
Let the baked bars sit 10 minutes in the pan, then lift them out with the parchment overhang for the cleanest cuts.
Drain Your Add-Ins
Pat thawed vegetables and cooked chicken dry with paper towels so extra moisture does not sabotage the set.
Pro Tips
Step-by-Step Instructions
1. Heat Oven and Prep Pan
Preheat the oven to 350F (175C) and line a 9×13-inch baking dish with parchment, leaving a 2-inch overhang on the long sides. Brush the parchment with 2 tablespoons of the melted butter so the crust releases cleanly.
2. Make the Crumb Crust
In a bowl, stir the crushed crackers with the remaining 4 tablespoons melted butter until the mixture looks like wet sand. Press it firmly and evenly into the pan, then bake at 350F (175C) for 8 minutes until it smells toasty and the edges just begin to brown.
3. Thicken the Filling
In a medium saucepan over medium heat, whisk the soup, garlic powder, and black pepper together and bring to a gentle simmer, about 3 minutes. Whisk in the cornstarch slurry and cook 2 minutes more, stirring constantly, until the filling thickly coats the back of a spoon.
4. Fold in the Add-Ins
Off the heat, stir in the thawed vegetables, shredded chicken if using, and 1/2 cup of the cheddar until evenly distributed. Taste and adjust salt, remembering the cracker crust is already seasoned.
5. Assemble the Bars
Pour the filling over the warm crust and spread it level with a spatula. Scatter the remaining 1/2 cup cheddar across the top, covering the surface so every slice gets a cheesy lid.
6. Bake Until Bubbling
Bake at 350F (175C) for 25 to 30 minutes, until the edges bubble steadily and the center registers 165F (74C) on an instant-read thermometer. The top should be melted, glossy, and lightly golden at the corners.
7. Cool and Set
Transfer the pan to a wire rack and cool 10 minutes in the pan, then refrigerate 30 minutes if you want ultra-clean slices. The filling firms as it cools, which is exactly what makes it sliceable.
8. Slice and Serve
Lift the slab out using the parchment overhang and cut into 6 generous squares with a sharp knife. Garnish with parsley and serve warm, when the cheese is still stretchy.
Delicious Variations
Chicken Pot Pie Bars
Use cream of chicken soup, add 1 cup diced cooked potatoes, and top with crushed butter crackers instead of cheddar.
Broccoli Cheddar Bars
Swap the mixed vegetables for 2 cups chopped steamed broccoli and use extra-sharp cheddar for a bolder, pub-style bite.
Spicy Taco Soup Bars
Use a creamy tomato soup base, add 1 tablespoon taco seasoning and a drained can of black beans, and finish with pepper jack.
How to Store Soup Bars
Refrigerator
Store cooled bars in an airtight container in the refrigerator for up to 4 days; layer with parchment so the cheese does not stick.
Freezer
Wrap individual squares tightly in plastic, then foil, and freeze up to 3 months; thaw overnight in the refrigerator before reheating.
Reheating
Reheat in a 350F (175C) oven for 10 to 12 minutes, or microwave single squares 60 to 90 seconds, until the center is hot and the cheese re-melts.
Frequently Asked Questions
Q: Can I make Soup Bars with canned soup?
Yes, canned cream-based soup works beautifully and is the fastest route to this recipe. Use two 10.5-ounce cans, add 1/4 cup milk to loosen, and still simmer with the cornstarch slurry so the filling sets firm.
Q: Why are my soup bars mushy?
They are almost always mushy because the filling was not thickened enough or the add-ins were wet. Simmer the slurry a full 2 minutes, drain your vegetables and chicken, and chill the baked pan 30 minutes before slicing.
Q: How long do soup bars last in the fridge?
Soup Bars keep 4 days in an airtight container in the refrigerator. Reheat single squares in the microwave for 60 to 90 seconds or in a 350F (175C) oven for 10 minutes.
Q: Can I make these soup bars gluten free?
Yes, use gluten-free buttery crackers or crushed gluten-free cornflakes for the crust. Check that your canned soup and cornstarch are certified gluten free, since some cream soups contain wheat flour.
Q: What is the best soup to use for soup bars?
Thick cream-based soups set best, so cream of mushroom, cream of chicken, or a pureed vegetable soup are top choices. Avoid brothy soups like minestrone unless you add extra cornstarch to compensate.
