When I told my mom that I was writing a book on casseroles, she immediately began digging into her old file box of handwritten recipes and gave me one for broccoli-spinach casserole. But the instructions were so wacky we couldnt make heads or tails of it. She told me that those handwritten recipes of hers from fifty years ago were really reminder notes more than anything, and so much time had passed that she was clueless as to its meaning, so we discussed how the recipe should look and this is what we came up with. When mom first made it in the 1950s she didnt have access to the extraordinary produce we do today, and this is a recipe begging for the best. Mom would have used store-bought croutons, but I usually make my own because I think theyre better. To make your own croutons, cut 2 to 4 slices of Italian or French bread into small cubes that should equal a cup then fry them in a non-stick skillet in 1 tablespoon of butter until golden. She would have also used Campbells Cream of Mushroom soup, but I make my own sauce. If you serve this casserole as a side dish, it is best with a simple main course, such as roast chicken.


Broccoli florets 3/4 Pound
Spinach 1 1/4 Pound , heavy stems removed, washed well
Finely chopped onion 1/4 Cup (4 tbs)
White mushrooms 1/4 Pound
Whole milk 1/2 Cup (8 tbs)
All purpose flour 2 Tablespoon
Salt 1/4 Teaspoon (Plus More As Needed)
Freshly ground black pepper 1/4 Teaspoon
Heavy cream 1/4 Cup (4 tbs)
Eggs 2 Large
Mayonnaise 1/4 Cup (4 tbs)
Shredded mild white cheddar cheese 3 Ounce (1 Cup)
Bread croutons 1 Cup (16 tbs) (For Stuffing, Small Plain Or Herbed)


1. Preheat the oven to 350 degrees F. Butter a 12 x 9 x 2-inch or similar casserole.

2. Bring a large saucepan of lightly salted water to a boil over high heat then boil the broccoli florets until tender and bright green, 6 minutes and not more. Remove the broccoli with a skimmer or slotted spoon and plunge them into a bowl of cold water to stop them from cooking. Drain the broccoli florets from the cold water after a couple of minutes and transfer them to a large bowl.

3. Meanwhile, keep the water in the saucepan at a boil, then add the spinach and cook until it wilts, about 1 minute. Drain the spinach well, squeezing the excess water out with your hands once it’s cool enough to handle. Chop the spinach and set aside in the bowl with the broccoli florets. Add the onion to the bowl and toss the vegetables well.

4. Place the mushrooms, milk, flour, a little salt and 1/8 teaspoon black pepper in a blender and blend until smooth. Add the heavy cream and blend briefly.

5. In a bowl, beat the eggs, then stir in the mayonnaise, reserved mushroom sauce from the blender, 1/4 teaspoon of salt, and 1/8 teaspoon of pepper. Add the cooked vegetables and toss well. Transfer to the buttered casserole.

6. In a bowl, combine the cheddar cheese and croutons, tossing to mix and then sprinkle on top of the vegetables. Bake until the cheese is melted and the edges of the casserole are bubbling, about 20 minutes. Serve hot.
