Cajun Spiced Stuffed Mushrooms

Cajun Spiced Stuffed Mushrooms are creamy, savory, and full of bold flavor from sautéed peppers, onions, and Cajun seasoning. Serve with crisp white wine, a simple green salad, or other bite-sized appetizers for easy entertaining.

Easy Mushroom Appetizer

These stuffed mushrooms are one of those appetizers that fit in anywhere, from casual get-togethers to holiday parties. The filling can be made ahead, which makes prep simple when entertaining. Adjusting the spice is easy too, so they work for both mild and heat-loving guests.

They hold up well on a platter, stay flavorful even after cooling slightly, and pair nicely with a variety of snacks or small bites.

Ingredients for Cajun Spiced Stuffed Mushrooms

Here’s what you’ll need. Exact amounts are listed in the printable recipe card at the bottom of the post.

• Olive Oil – For sautéing the veggies until tender and fragrant.
• Onion and Garlic – The savory, aromatic base that keeps the flavor balanced.
• Bell Peppers – Red and green peppers add a pop of color and a touch of sweetness.
• Jalapeño Pepper – Brings a gentle kick; keep the seeds for more spice or remove them for a milder version.
• Cajun Seasoning – A bold mix of paprika, cayenne, garlic, onion, oregano, and thyme that gives the filling its signature Southern flavor.
• Cream Cheese – Full-fat works best for a smooth, rich filling that stays creamy as it bakes.
• Parsley – Adds a fresh finish and bright color to the filling.
• Cremini Mushrooms (Baby Bellas) – Choose mushrooms about 1½ to 2 inches wide—large enough to hold plenty of filling but still bite-sized for easy serving. White button mushrooms also work, but creminis have a richer flavor and tend to hold up better in the oven.

How to Make Cajun Spiced Stuffed Mushrooms

STEP ONE: Preheat.
Preheat oven to 350°F.

STEP TWO: Sauté the Vegetables.
In a skillet over medium-high heat, add olive oil. When hot, add the onion, green pepper, red pepper, and jalapeño. Cook, stirring often, for 3–4 minutes until softened.

STEP THREE: Add Garlic and Seasoning.
Stir in garlic and Cajun seasoning. Cook 1–2 minutes more, then remove from heat.

STEP FOUR: Mix the Filling.
Add cream cheese and parsley. Stir until the mixture is smooth and evenly blended.

STEP FIVE: Stuff and Bake.
Spoon the filling into mushroom caps, pressing lightly to fill. Arrange them on a baking sheet and bake for 12–15 minutes, until the mushrooms are tender and the tops are lightly browned. Serve warm.

Make It Vegan 🌱

• For a plant-based appetizer, swap the cream cheese for a dairy-free version

 Storage and Reheating

• These stuffed mushrooms are best served fresh. If you have leftovers, store them in an airtight container in the refrigerator.
• Reheat in a 350°F oven for about 10 minutes, just until heated through. Microwaving is not recommended; the mushrooms can turn soft and lose their texture.
