- Homemade sauce: A creamy béchamel flavored with a dash of heat — no canned soup required.

Ingredients
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh green beans | 2 lbs | Ends trimmed, halved crosswise |
| Kosher salt | 1 1/2 tsp, plus extra | For seasoning and boiling water |
| Olive oil | 1 tbsp + 1 tsp | Divided use |
| Bacon | 4 strips | Chopped |
| Garlic cloves | 3 | Chopped |
| Celery stalks | 2 | Chopped |
| Small onion | 1 | Chopped |
| Red bell pepper | 1 | Chopped |
| Cajun seasoning | 1 tbsp + 1 tsp | Divided |
| Salted butter | 4 tbsp | |
| All-purpose flour | 1/4 cup | |
| Whole milk | 2 1/2 cups | |
| Half-and-half | 1/2 cup | |
| Hot sauce | 2 tsp | Your favorite brand |
| Crispy fried onions | 2 (2.8 oz) cans, ~3 cups |
Step-by-Step Directions
- Preheat the oven: Set to 375°F (190°C). Prepare a large pot of generously salted water for blanching.
- Blanch the green beans: Add trimmed green beans to boiling water. Cook until bright green and crisp-tender (3–4 minutes). Drain and immediately run under cold water or place in an ice bath to stop cooking. Pat dry for the best casserole texture.
- Cook the bacon and veggies: Heat 1 tablespoon olive oil in a large skillet over medium heat. Add chopped bacon and cook, stirring, until just crisp (3–4 minutes). Mix in garlic, celery, onion, and bell pepper. Sauté until vegetables soften, about 5 minutes. Stir in 1 tablespoon Cajun seasoning. Remove from heat.
- Make the creamy sauce: In a large Dutch oven or heavy saucepan, melt butter over medium-low heat. Sprinkle in the flour and stir to form a smooth paste; cook 2 minutes. Gradually whisk in whole milk and half-and-half. Simmer gently until sauce thickens and becomes velvety (about 2 minutes). Whisk in hot sauce and 1 1/2 teaspoons salt for depth and heat.
- Assemble the casserole: Fold the bacon-vegetable mixture and blanched green beans into the sauce. Stir to coat everything evenly. Pour the entire mixture into a 9-by-13-inch baking dish, smoothing the top.
- Prepare the topping: In a medium bowl, toss crispy fried onions with remaining olive oil and 1 teaspoon Cajun seasoning. Scatter over the surface of the casserole for even, spicy crunch.
- Bake: Place casserole in the oven and bake until bubbly and the onions are golden brown, about 15 minutes. Serve hot and enjoy the warm, robust flavors.
Recipe Tips & Variations
- Fresh is best: Use fresh green beans for optimal texture. Frozen or canned beans can be used but may yield a softer result.
- Smokier flavor: Try smoked paprika or chipotle powder with the Cajun seasoning for added depth.
- Make it vegetarian: Omit the bacon and sauté veggies in olive oil or butter; add smoked salt for complexity.
- Dairy-free adaptation: Substitute plant-based butter, unsweetened oat milk, and coconut cream for the milk and half-and-half.
- Add cheese: For a meltier casserole, stir in a cup of grated sharp cheddar or pepper jack with the sauce.
- Customize the heat: Add cayenne or more hot sauce for a spicier kick, or tone it down for milder tastes.

Storage & Make-Ahead Tips

Frequently Asked Questions (FAQs)
What makes this casserole Cajun?
It’s the generous use of Cajun seasoning, which blends paprika, garlic powder, onion powder, cayenne, and often herbs like thyme, plus the use of the ‘trinity’ of veggies (onion, celery, bell pepper) and a hit of hot sauce for a layered, zesty flavor.
What others are reading
Can I use a homemade Cajun seasoning?
Yes. Mix paprika, garlic and onion powders, thyme, oregano, black and white peppers, and cayenne to your taste for a personalized blend.
Should I use fresh, frozen, or canned green beans?
Fresh green beans provide the best texture and color. Frozen may be used (thaw and pat dry), while canned will be much softer and less crisp.
Is it spicy?
It has a moderate heat from Cajun seasoning and hot sauce, but you can easily adjust for your preferred spice level.
What’s the best way to get a crispy topping?
Toss store-bought fried onions with extra oil and seasoning moments before baking, and bake uncovered for 10–15 minutes until golden and crisp.
