Ingredient Notes
Let’s geek out over the stars of this dish:
- Fresh asparagus: Thick spears hold up best (trim woody ends!). *Pencil-thin? Reduce bake time by 5 mins.*
- Sharp cheddar: Freshly grated melts smoother than pre-shredded. Swap with smoked gouda for depth!
- Ritz crackers: 1 sleeve = 35 crackers. Crush in the bag to save time (and crumbs!).
- Homemade roux: Butter + flour + milk base (no canned soup!). *For gluten-free, use 1:1 GF flour.*
- Secret ingredient: Mayo adds creaminess without heaviness. Greek yogurt works but adds tang.

How To Make Asparagus Cracker Casserole
- Prep the Asparagus: Trim ends, cut into 2-inch pieces. No mushy stems!
- Make the Cheese Sauce:
- Melt butter, whisk in flour to form a roux (cook 1 minute to kill raw flour taste).
- Gradually pour in milk while whisking aggressively—no lumps allowed!
- Stir in shredded cheddar, mayo, garlic powder, onion powder, S+P until silky.
- Assemble: Toss asparagus in sauce, spread into greased 9×13 dish.
- Top & Bake:
- Crush Ritz, mix with melted butter, sprinkle over casserole.
- Bake at 375°F for 40-45 mins until bubbly. Broil 2-3 mins for extra crunch!
Pro Tips for Success
- Avoid Soggy Topping: Let sauce cool slightly before adding crackers. Pat asparagus bone-dry after rinsing.
- Crispier Crust Hack: Add a second layer of crackers halfway through baking.
- Make Ahead: Assemble (unbaked) and refrigerate for 24 hours. Add 5-7 mins to bake time.
- Freezer-Friendly: Freeze unbaked casserole for up to 3 months. Thaw overnight before baking.

Serving Suggestions
- Holidays: Pair with honey-glazed ham or herb-roasted turkey.
- Weeknights: Serve alongside air-fryer chicken thighs or garlic butter salmon.
- Vegetarian Main: Add a fried egg on top for protein!
- Dips: Ranch, hot sauce, or lemon aioli for dunking.
Storage and Reheating
Leftovers? Cover tightly and fridge for 3-4 days. Freeze for up to 2 months (thaw overnight before reheating).
Reheat: Microwave slices for speed, but the oven (350°F, 15-20 mins) revives the cracker crunch. Pro tip: Add fresh cracker crumbs post-reheat for bonus crispiness.
Make-Ahead Options
This asparagus cracker casserole is perfect for planning ahead:
- Fully Assembled, Not Baked: Assemble the casserole without the cracker topping, cover tightly, and refrigerate for up to 24 hours. Add the cracker topping just before baking and extend baking time by about 10 minutes.
- Partially Prepared: Blanch the asparagus and make the béchamel sauce up to 2 days ahead. Store separately in the refrigerator, then assemble and bake when ready.
- Freezer Option: While fresh is best, you can freeze the unbaked casserole (without cracker topping) for up to 1 month. Thaw completely in the refrigerator overnight, add the topping, and bake as directed.
Variations and Substitutions
- Cheese Swap: Gruyère or smoked gouda for a fancy twist.
- Veggie Vibes: Swap asparagus for broccoli or green beans (blanch first!).
- Cracker Chaos: Use Cheez-Its for extra cheesiness or gluten-free crackers.
- Meat Lovers: Bacon bits or diced ham turn it into a main dish.
- Lighter Twist: Substitute half the mayo with Greek yogurt (but we warned you about the tang).
If casseroles had a personality, this one would be the life of the party—unpretentious, reliable, and secretly impressive. It’s the dish that’ll have your Thanksgiving guests begging for the recipe and your kids eating vegetables without a negotiation. Between the creamy-cheesy base, the veggie crunch, and that obsession-worthy Ritz topping, it’s comfort food with a gourmet wink. Whip it up, watch it disappear, and prepare to be dubbed the casserole wizard of your friend group. (Cape optional, but highly encouraged.)
Can I use frozen asparagus?
Yes! Thaw completely and squeeze out excess moisture to prevent a watery sauce.
How do I keep the crackers from getting soggy?
Let the cheese sauce cool for 10 mins before adding the topping. Broil at the end!
Can I substitute Ritz crackers?
Try Cheez-Its (extra cheesy!), saltines, or gluten-free crackers. Avoid breadcrumbs—they lack buttery flavor.
Is this casserole keto-friendly?
Swap Ritz for crushed pork rinds and use almond flour in the roux (carbs: 6g/serving).
Why does my sauce taste bland?
Underseasoning is the culprit! Taste the sauce before baking and add extra garlic powder or a pinch of cayenne.
Asparagus Cracker Casserole
Ingredients
- 2 lbs fresh asparagus ends trimmed and cut into 2-inch pieces
- ½ cup mayonnaise
- 1 cup shredded sharp cheddar cheese
- 2 tbsp unsalted butter
- 2 tbsp all-purpose flour
- 1 cup whole milk
- ½ tsp garlic powder
- ½ tsp onion powder
- 15 butter crackers such as Ritz, finely crushed
- Kosher salt and freshly ground black pepper to taste
Instructions
- Preheat Oven: Adjust oven rack to the center position and preheat to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Prepare Asparagus Mixture: In a large mixing bowl, combine asparagus, mayonnaise, and shredded cheddar cheese. Stir gently until evenly coated. Set aside.
- Make the Roux: In a medium saucepan over medium heat, melt butter. Add flour and cook, whisking constantly, for 1–2 minutes until the mixture turns lightly golden and fragrant.
- Prepare Cream Sauce: Gradually pour in milk while whisking continuously to prevent lumps. Bring the mixture to a gentle simmer, whisking frequently, until thickened enough to coat the back of a spoon (3–4 minutes).
- Season and Combine: Remove saucepan from heat. Stir in garlic powder, onion powder, ½ tsp salt, and ¼ tsp black pepper. Pour sauce over the asparagus mixture and fold gently until fully incorporated.
- Assemble and Bake: Transfer mixture to the prepared baking dish and spread evenly. Sprinkle crushed crackers in an even layer over the top. Bake for 40–50 minutes, or until the casserole is bubbly and the cracker topping is golden brown.
- Optional Broiling: For added crispiness, broil the casserole on high for 1–2 minutes, watching closely to prevent burning.
- Serve: Let rest for 5 minutes before serving. Garnish with freshly cracked pepper or additional cheese, if desired.
