Holly’s Recipe Highlights
- Flavor: Creamy, comforting asparagus casserole is a belly-warming dish.
- Difficulty: It’s so easy. Just cook asparagus, whisk the sauce, bake, and top with cheese.
- Budget tip: Mix in leftover rice or pasta to stretch the dish.
- Serving suggestions: Serve alongside chicken, pork chops, or roast turkey.
Creamy Casserole Components
Asparagus: Frozen asparagus takes the prep work out of using fresh since they are already pre-cut. If using fresh, snap the woody stems off and cut each piece into 2-3” pieces and include the tips.
Cheese: Just like broccoli and cheddar, asparagus and cheddar are a perfect combo.
Sauce: A can of cream of mushroom soup is a big timesaver in this recipe, and there’s no need to buy the name brand.
Topping: Crispy fried onions are super versatile for everything from soups to burgers and salad toppings.
Creative Customizations
- Use bacon bits or slivered almonds instead of fried onions for a crispy topping swap. Add some sliced mushrooms or sundried tomatoes.
- You can make fried onions if you can’t find a can of them, and they’re as tasty and savory as the store-bought kind.
- Other soups to try are cream of celery or cream of chicken. Any non-dairy milk can also be used instead of regular milk.
- When it comes to cheese, you can also use shredded Monterey Jack, Swiss cheese, or a Mexican blend for different flavor profiles.
