Step-by-Step Instructions to Make The Best Broccoli Casserole Vintage Recipe
Preheat and Prepare the Dish
Heat the oven to 350°F. Grease a 9×13 inch baking dish with 1 tsp butter or nonstick spray.
Blanch the Broccoli
Bring a large pot of salted water to a boil. Add broccoli florets and blanch for 2 minutes until vibrant green and just crisp-tender. Drain and plunge into an ice bath to stop cooking. Drain very well and pat dry so the casserole is not watery.
Sauté Aromatics
In a skillet over medium heat, melt 1 tbsp butter. Cook the onion until soft, 4 to 5 minutes. Add garlic and cook 30 seconds. Remove from heat.
Mix the Creamy Base
In a large bowl, whisk together cream of mushroom soup, mayonnaise, and milk until smooth. Stir in the sautéed onion mixture, 1 1/2 cups shredded cheddar, smoked paprika, a pinch of salt, several grinds of pepper, and lemon juice if using.
Combine and Fill the Dish
Add the well-drained broccoli to the bowl and fold gently to coat. Spread the mixture evenly in the prepared baking dish and smooth the top.
Make the Buttery Cracker Topping
Melt remaining 3 tbsp butter. In a bowl, combine crushed crackers, Parmesan, and melted butter until evenly moistened. Sprinkle over the casserole. Top with remaining 1/2 cup cheddar.
Bake Until Golden and Bubbly
Bake uncovered for 25 to 30 minutes, until the edges are bubbling and the top is golden. If needed, broil for 1 to 2 minutes for extra color. Let rest 10 minutes to set before serving.
Optional From-Scratch Sauce (No Condensed Soup)
For the sauce, melt 3 tbsp butter in a saucepan over medium heat. Whisk in 3 tbsp all-purpose flour and cook 1 minute. Slowly whisk in 1 1/2 cups milk until smooth. Simmer 3 to 4 minutes until thick. Season with 1/2 tsp kosher salt, 1/4 tsp pepper, and a pinch of paprika. Use in place of the canned soup.
Tips for Success
- Do not skip the blanch-and-chill step. It keeps broccoli bright and prevents mushiness.
- Dry the broccoli thoroughly so the sauce stays creamy, not watery.
- Shred your own cheese for the smoothest melt. Pre-shredded can be coated with starch.
- Season in layers. Taste the sauce before combining with broccoli and adjust salt and pepper.
- Add the topping just before baking so it stays crisp.
Variations of The Best Broccoli Casserole Vintage Recipe
- Chicken and Rice: Fold in 2 cups cooked diced chicken and 1 cup cooked rice, then bake.
- Bacon Cheddar: Add 1/2 cup cooked, crumbled bacon for smoky richness.
- Mushroom Lovers: Sauté 8 oz sliced mushrooms with the onion and use Gruyere cheese.
- Spicy Kick: Stir in 1 finely chopped jalapeño or 1/4 tsp cayenne.
- Gluten Free: Use gluten free crackers and from-scratch sauce with gluten free flour.

Storage & Reheating Instructions
- Refrigerate: Cover and store leftovers for 3 to 4 days.
- Reheat: Warm at 350°F, uncovered, 15 to 20 minutes, or microwave individual portions 60 to 90 seconds. Broil briefly to re-crisp the topping.
- Freeze: Wrap tightly and freeze up to 2 months. Thaw overnight in the fridge, add fresh cracker topping if needed, then bake until hot.
Memories Made Around the Table
My grandmother set this on the table in a floral Pyrex, and you could hear the crunch of the topping as the first spoon broke through. It is the dish everyone asked for, and the one that always went home empty.
FAQs
Can I use frozen broccoli?
Yes. Thaw completely, then drain and pat dry. If very wet, spread on a towel-lined sheet pan to remove excess moisture before mixing.
Can I make this ahead?
Assemble up to 2 days in advance without the topping. Cover and refrigerate. Add the cracker topping just before baking, then bake 30 to 35 minutes.
What can I use instead of condensed soup?
Use the from-scratch white sauce in the instructions. It is a quick roux with milk that delivers the same creamy texture with simple pantry ingredients.
How do I keep the topping crunchy?
Bake uncovered and add the topping right before baking. For extra crunch, broil 1 to 2 minutes at the end, watching closely.
Is this vegetarian?
Yes if you use cream of mushroom soup or the homemade sauce with vegetable stock and vegetarian Parmesan-style cheese.
