Four Cheese Mushroom Toasts Recipe | Cheesy, Savory & Delicious

I still remember the first time I made these Four Cheese Mushroom Toasts — the smell alone had me hovering near the oven like a kid waiting for cookies. The mix of gooey cheeses, golden mushrooms, and crisp sourdough created the perfect comfort snack. The whole thing came together so effortlessly that I knew I had to make it again.

Today, I’m excited to walk you through exactly how I recreate this rich, savory, cheesy toast at home. Trust me, you’re going to love how simple and satisfying it is. If you enjoy rich and savory meals, you might also like this Beef Drunken Noodles Recipe for an equally indulgent dinner.

Ingredients

Here’s everything you need to make these incredibly indulgent toasts, along with small notes on why each ingredient works so well.

400 g sliced cremini mushrooms — they bring an earthy, meaty flavor that holds up beautifully against the richness of the cheese.
2 tbsp salted butter — adds depth and helps the mushrooms brown perfectly.
1 tbsp olive oil — prevents the butter from burning and gives extra flavor.
1 tbsp Worcestershire sauce — creates a deeper, savory mushroom flavor.
¼ tsp salt — seasons the mushrooms lightly.
¼ tsp ground black pepper — gives a touch of warmth.
½ cup mayonnaise — forms a creamy base for the cheese mixture.
¼ cup sour cream — balances the richness with gentle tanginess.
2 tbsp melted butter — adds extra creaminess to the cheese spread.
2 cloves garlic, minced — sharp flavor that complements the mushrooms.
1 tbsp dried onion flakes — gives onion flavor without adding moisture.
¼ tsp ground black pepper — rounds out the taste.
½ cup grated Parmesan cheese — salty and sharp, adds depth.
½ cup grated Havarti cheese — buttery and melty for smooth texture.
½ cup grated Swiss cheese — nutty flavor pairs beautifully with mushrooms.
½ cup grated Mozzarella cheese — adds stretch and gooeyness.
¼ cup sliced green onions — bright and fresh, adds contrast.
4 slices sourdough bread — sturdy enough to hold the toppings without getting soggy.

Note: Serves 4 (makes 4 loaded toasts). For a slightly sweeter twist alongside this savory toast, try pairing it with Maple Pecan Roasted Acorn Squash Recipe, which brings a warm, nutty complement.

Variations

You can easily adjust this recipe to match your taste or dietary needs.

Swap in plant-based cheese, vegan mayo, and dairy-free sour cream for a fully dairy-free version.
Use gluten-free bread if needed.
Add fresh herbs like parsley, thyme, or chives for extra aroma.
Add crushed chili flakes for a spicy twist.
Mix roasted veggies into the mushrooms for more texture and color.
Use any cheese you love — gruyere, white cheddar, or provolone also work great.

How to Make Four Cheese Mushroom Toasts

A simple process with rich, delicious results.

Cook the Mushrooms

Heat the butter and olive oil in a skillet over medium-high heat until the butter melts. Add the sliced mushrooms, along with salt and pepper, and let them cook for about five minutes. Stir occasionally until they start to brown, then add the Worcestershire sauce and cook another few minutes until the mushrooms turn golden and flavorful. Let them cool and set aside some pretty slices for topping.

Prepare the Cheese Spread

In a bowl, mix the mayonnaise, sour cream, and melted butter until smooth. Add the garlic, onion flakes, and pepper. Fold in all the grated cheeses and sliced green onions until fully combined. This mixture should be thick, creamy, and rich.

Toast the Bread

Place the sourdough slices on a baking sheet and toast under the broiler until lightly golden. Flip the bread and toast the other side as well. Let the bread cool slightly — warm, not hot — so the topping spreads easily.

Assemble and Broil

Mix the cooled mushrooms (except the reserved slices) into the cheese mixture. Spread this mushroom-cheese filling generously on each toasted bread slice. Top with the reserved mushroom slices for a nice finish. Broil until the cheese bubbles and turns golden brown. Watch closely — it only takes a few minutes.

Additional Tips for Making This Recipe Better

Here are little things I’ve learned while making this recipe multiple times:

I always grate the cheese fresh — pre-shredded cheese never melts as beautifully.
I let the mushrooms brown deeply for maximum flavor.
Cooling the mushrooms fully keeps the cheese mixture from becoming oily.
I spread the topping thickly because more cheese always means better toast.
I stay near the oven while broiling — the perfect golden top can become burnt quickly.

How to Serve Four Cheese Mushroom Toasts

These toasts are best eaten hot when the cheese is bubbly and the bread is crisp. I like slicing them diagonally for a nicer presentation. Garnish with extra green onions or fresh herbs. They pair beautifully with tomato soup, a green salad, or even a brunch spread with eggs and fruit. Serve on a warm plate for an extra cozy touch.

Make Ahead and Storage

Storage

Store any leftover toasts in an airtight container in the refrigerator. They stay fresh for about 1–2 days, though the bread softens slightly.

Freezing

The cheese mixture freezes well for up to one month. Freeze it separately and thaw before using. The cooked mushrooms and assembled toasts do not freeze well.

Reheating

Reheat in the oven or air fryer at 350°F until warm and crisp again. Avoid microwaving — it makes the bread soggy and ruins the texture.
