Aunt Naomi’s Famous Asparagus (or Broccoli!) Casserole

The scent of this casserole instantly transports me back to childhood vacations. I can almost feel the humid Hilton Head air, hear the cicadas buzzing, and see my cousins running wild on the beach. But most vividly, I remember the comforting aroma wafting from the kitchen as my Aunt Naomi, a whirlwind of energy and floral prints, prepared this very dish. It was always a family favorite, a simple yet satisfying side that somehow managed to disappear within minutes of being set on the table. It’s a taste of sunshine and family, all baked into one golden dish.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 45 minutes
Total Time: 1 hour 5 minutes
Servings: 10-12
Yield: One 9×13 inch casserole
Dietary Type: Varies (See Variations & Substitutions)

Ingredients

1 (10 1/4 ounce) can cream of mushroom soup
2 eggs, well beaten
1 cup mayonnaise
1 medium onion, chopped
2 (10 ounce) boxes frozen asparagus or 2 (10 ounce) boxes frozen broccoli, partially cooked
1 (6 ounce) box Stove Top Savory Herb Stuffing Mix
2 1/2 cups boiling water
8 tablespoons (1 stick) butter or margarine
1 cup shredded cheddar cheese

Equipment Needed

Large Mixing Bowl
2-Quart Baking Dish (9×13 inch)
Saucepan
Measuring Cups and Spoons
Cutting board
Knife

Instructions

Preheat your oven to 350°F (175°C). Make sure the rack is in the center position for even baking.
While the oven is preheating, prepare the Stove Top Stuffing Mix. In a saucepan, bring 2 1/2 cups of water to a rolling boil. Add 8 tablespoons (1 stick) of butter or margarine to the boiling water and let it melt completely.
Remove the saucepan from the heat and stir in the entire box of Stove Top Savory Herb Stuffing Mix. Fluff with a fork and set aside. This allows the stuffing to properly hydrate and develop its flavor.
In a large mixing bowl, combine the cream of mushroom soup, eggs, mayonnaise, and chopped onion. Whisk these ingredients together until well blended and smooth. This creates the creamy base for the casserole.
If using frozen asparagus or broccoli, partially cook it according to the package directions. You want it tender-crisp, not completely mushy. Overcooked vegetables will become soggy in the casserole. Drain well.
Add the partially cooked asparagus or broccoli to the mixing bowl with the soup mixture. Gently fold in the vegetables, making sure they are evenly coated.
Now, incorporate the prepared Stove Top Stuffing Mix into the vegetable and soup mixture. Stir gently until everything is well combined. Avoid overmixing, as this can make the casserole dense.
Grease a 2-quart baking dish (9×13 inch) with butter, margarine, or cooking spray. This will prevent the casserole from sticking and make serving easier.
Pour the casserole mixture into the prepared baking dish, spreading it evenly.
Sprinkle the shredded cheddar cheese evenly over the top of the casserole. This creates a delicious, golden-brown crust.
Bake in the preheated oven for 45 minutes, or until the casserole is heated through, bubbly, and the cheese is melted and lightly browned. Check for doneness by inserting a knife into the center of the casserole. If it comes out clean, it’s ready.
Remove the casserole from the oven and let it rest for a few minutes before serving. This allows the casserole to set slightly and makes it easier to cut.

Expert Tips & Tricks

Partial cooking is key: Don’t fully cook the asparagus or broccoli beforehand. It will continue to cook in the oven and you want to avoid a mushy texture.
Cheese variation: Feel free to experiment with different types of cheese. Gruyere, Monterey Jack, or even a sharp provolone would be delicious alternatives to cheddar.
Make-ahead option: You can assemble the casserole up to 24 hours in advance. Cover it tightly with plastic wrap and refrigerate. Add about 10-15 minutes to the baking time if baking directly from the refrigerator.
Crispy topping: For an extra crispy topping, sprinkle some panko breadcrumbs over the cheese before baking.
Prevent burning: If the cheese starts to brown too quickly, tent the casserole with aluminum foil during the last 15 minutes of baking.

Serving & Storage Suggestions

Serve this asparagus or broccoli casserole hot as a side dish alongside roasted chicken, ham, or beef. It’s also a great addition to holiday meals.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, or microwave in short intervals, stirring occasionally, until warmed. You can also freeze the casserole for up to 2 months. Thaw overnight in the refrigerator before reheating. Be aware that the texture might change slightly after freezing.

Variations & Substitutions

Gluten-Free: Use gluten-free stuffing mix and ensure your cream of mushroom soup is also gluten-free.
Dairy-Free/Vegan: Substitute the cream of mushroom soup with a vegan cream of mushroom soup (many brands are available). Use a vegan mayonnaise alternative and omit the cheddar cheese, or replace it with a vegan shredded cheese alternative. Melted nutritional yeast can also be used to add a cheesy flavor. Use olive oil instead of butter or margarine.
Different Vegetables: Get creative! Try adding other vegetables like cauliflower, green beans, or even some chopped red bell pepper for added color and flavor.
Meat Lovers: Add cooked and crumbled bacon or sausage for a heartier casserole.
Spice it up: Add a pinch of red pepper flakes to the soup mixture for a subtle kick.

FAQs (Frequently Asked Questions)

Q: Can I use fresh asparagus or broccoli instead of frozen?
A: Yes, you can! Just be sure to trim the asparagus and chop the broccoli into bite-sized pieces. You’ll still want to partially cook them before adding them to the casserole.

Q: Can I make this casserole without the Stove Top Stuffing Mix?
A: The stuffing mix adds a lot of flavor and texture, but if you don’t have it on hand, you could try substituting it with breadcrumbs or crushed crackers mixed with herbs and melted butter.

Q: My casserole seems watery. What did I do wrong?
A: This usually happens when the vegetables aren’t drained properly after being partially cooked. Make sure to drain them well before adding them to the casserole mixture.

Q: Can I use a different kind of soup?
A: While cream of mushroom soup is traditional, you could experiment with other cream-based soups, like cream of celery or cream of chicken. The flavor will change slightly, but it can still be delicious.

Q: How do I prevent the cheese from burning?
A: If the cheese starts to brown too quickly, tent the casserole with aluminum foil during the last 15 minutes of baking.
