Spread the creamy mixture evenly into your prepared baking dish This layer guarantees the topping crisps throughout

Bake Until Golden:

The Gruyère cheese is my secret for depth and melted richness Often I will slip in a dash extra just before baking It is the ingredient that gets the most compliments and makes the sauce stretch over every vegetable I still remember how last winter no one touched other dishes after tasting this one

Flavor Boosters

Let leftovers cool fully before covering and refrigerate They will keep fresh for three days and only need gentle reheating so the sauce stays creamy For the freezer wrap the unbaked casserole tightly in plastic and foil Freeze for up to three months Thaw overnight and bake as usual adding ten minutes if needed If baking from chilled cover loosely with foil for the first half to keep the topping from over browning then uncover for the crispiest finish

Serving Suggestions

Serve hot alongside crusty bread or a leafy green salad for balance As a main dish add a can of white beans or a cup of cooked quinoa before baking For a special touch garnish with extra herbs or a sprinkle of fresh cracked pepper

Creative Twists

Swap in any winter vegetables you love or whatever is plentiful at the market Sweet potatoes turnip or even a bit of kale work well For a gluten free version use gluten free breadcrumbs and check labels on your canned soups Vegan cheese blends melt best for dairy free needs and using oat or almond milk keeps the base just as creamy

What You Need

02 1 can (10.5 ounces) cream of mushroom soup or cream of celery soup
03 1/2 cup whole milk or unsweetened plant-based milk
04 3 ounces Gruyère or cheddar cheese, freshly shredded

10 2 tablespoons unsalted butter, melted (or plant-based butter for dairy-free)

→ Optional Additions

11 1 cup cooked quinoa or canned white beans, drained and rinsed (for extra protein)

How to Make It

Step 01

Set oven to 375°F (190°C) and lightly grease a medium baking dish to prevent sticking and promote a golden crust.

Step 02

Dice fresh vegetables into even pieces, then steam or blanch for 3–4 minutes until fork-tender but still vibrant. Drain thoroughly. For frozen vegetables, thaw and pat dry.

Step 03

In a large mixing bowl, add prepared vegetables, cream soup, milk, shredded cheese, thyme, garlic powder, salt, and pepper. Stir thoroughly to coat all pieces evenly.

Step 04

Transfer the vegetable mixture to the greased baking dish and spread into an even layer using a spatula.

Step 05

In a small bowl, mix breadcrumbs with melted butter until evenly coated. Distribute topping over casserole for even coverage.

Step 06

Bake uncovered on the center rack for 25–30 minutes, or until the topping is golden brown and the sauce bubbles at the edges.

Step 07

Remove from oven and let stand 5–10 minutes before serving to allow sauce to set.

Extra Tips

  1. For gluten-free preparation, use certified gluten-free breadcrumbs and soup base. Dairy-free versions require plant-based cheese, milk, soup, and butter.
  2. Freeze the assembled, unbaked dish tightly wrapped for up to three months. Thaw overnight in the refrigerator before baking.
  3. Shredding your own cheese ensures a creamier sauce, as pre-shredded cheese may not melt as smoothly.
  4. Steam vegetables until just tender-crisp to prevent them from becoming mushy during baking.
