This healthy Broccoli Casserole is made from scratch (no canned soup) focusing on fresh ingredients and lightened-up swaps, all topped with crushed Ritz crackers. All the indulgent flavor with fewer calories, perfect for the holidays.

Broccoli Casserole

When it comes to comfort food, broccoli casserole is an undeniable classic. Creamy, cheesy, and topped with a crunchy layer of buttery crackers, it’s the kind of dish that graces many holiday tables. But as much as we love it, the traditional recipe can feel a little heavy—loaded with mayo, condensed soups, and more
richness than we sometimes want in a side dish. This revamped version retains all the flavors you know and love but lightens things up with smarter swaps and homemade touches. It’s the same cozy, satisfying dish but with a more modern twist! For more healthy vegetable casseroles, try my Spinach Gratin, Cauliflower “Mac” and Cheese, and Zucchini Casserole.

What Makes This Broccoli Casserole Special?

I love when I get recipe make-over requests. Someone recently asked me to make this dish over. It’s not a dish I typically make, so when I saw the ingredients using a cup of mayo and canned cream soups, I knew I would have to get creative.

• A Creamy Base without Overindulgence: Instead of a cup of mayonnaise or a store-bought condensed soup, this recipe uses light sour cream, a touch of mayo, and a homemade cream of mushroom soup substitute. The result is a creamy base lower in sodium and free of unnecessary preservatives.
• A Crisp Topping without Extra Butter: By reducing the amount of crushed crackers and skipping the melted butter, we keep the golden crunch while cutting back on unnecessary fat.
• Wholesome Ingredients: Freshly sautéed mushrooms and garlic are used to make homemade creamy mushroom soup without the heaviness of processed options.
• Dietary Restrictions: Weight Watchers-friendly, vegetarian

What to Serve with Broccoli Casserole

The next day, let it sit on the counter while the oven preheats. Sprinkle it with the crushed crackers, spray the top with oil, and bake it for the instructed time until it’s warmed through.
• Refrigerate leftovers in an airtight container for 4 days.
• Reheat the broccoli in the microwave until warm.
