Finding a crowd-pleasing side dish that’s both comforting and easy to make can feel like a real challenge. Between juggling work, family commitments, and trying to get dinner on the table, we often fall back on the same old steamed vegetables night after night. That’s where this asparagus casserole with Ritz crackers comes to the rescue – it’s a straightforward dish that combines fresh asparagus with a creamy sauce and that familiar, buttery crunch of Ritz crackers that everyone loves. Plus, it’s the kind of recipe you can throw together while helping with homework or catching up on other household tasks.

Possible Ingredient Alternatives
Asparagus can be replaced with green beans or broccoli florets for a similar texture and nutritional profile. Adjust cooking time slightly, as these vegetables may require different cooking durations. Mayonnaise can be substituted with Greek yogurt or a plant-based mayo alternative for a healthier or dairy-free option. Use the same amount, but expect a slightly tangier flavor with Greek yogurt. Sharp cheddar cheese can be swapped with Gruyère or a dairy-free cheese substitute for those avoiding dairy. Gruyère will provide a similar sharp flavor, while dairy-free alternatives may require additional seasoning to compensate for flavor differences. For a gluten-free version, replace the all-purpose flour with cornstarch or a gluten-free flour blend, using about half the amount of cornstarch as flour.

Ingredients
- 2 pounds asparagus (trimmed and sliced into 2-inch sections)
- 1/2 cup mayonnaise
- 6 ounces grated sharp cheddar cheese
- 1/2 onion (finely diced)
- 2 tablespoons all-purpose flour
- 2 minced garlic cloves
- 1 cup milk
- Salt and pepper to taste
- 15 crushed ritz crackers or similar
Step 1: Prepare and Combine Asparagus, Mayo, and Cheese
Start by placing your prepared asparagus, mayonnaise, and cheese together in a large bowl.
Set this bowl aside for later use as you prepare the other components of the dish.
Step 2: Saute the Onion and Create a Roux
In a skillet over medium heat, add a drizzle of oil and your chopped onion.
Sauté the onion for about 5 minutes until it’s soft and slightly browned.
Sprinkle the garlic and flour evenly over the onion mixture.
Stir continuously to create a roux, and allow the flour to cook for a minute or two.
Step 3: Prepare the Milk Sauce
Slowly pour the milk into the skillet, stirring constantly to incorporate it smoothly into the flour mixture.
Once combined, let the milk sauce come to a gentle bubble.
Add salt and pepper to taste, ensuring the sauce is well seasoned.
Continue cooking until the sauce thickens slightly.
Step 4: Combine All Ingredients and Prepare for Baking
Pour the thickened milk sauce into the bowl with the asparagus, mayo, and cheese.
Stir well to mix everything together.
Once mixed, transfer the combined ingredients into a 9×13-inch (or similar size) baking dish.
Evenly sprinkle the crushed crackers over the top of the casserole.
Step 5: Bake the Casserole
Preheat your oven to 375°F (190°C).
Bake the asparagus casserole for 40-50 minutes, or until the asparagus is just tender and the cheese is bubbly.
If a browned top is desired, broil the casserole for an additional minute.
Once finished, remove from the oven, serve immediately, and enjoy this flavorful dish!
