The Ingredients & Substitutions

- Spaghetti is excellent at holding onto our creamy sauce. Linguine or Fettuccine would make worthy substitutes.
- Olive oil. Its subtly fruity flavor provides an excellent base for sautéing our jalapenos and garlic.
- Jalapeno. The jalapenos are the flavor providers. They add that exciting heat and a unique tangy-spicy flavor, making the dish lively and vibrant.
- Garlic. It brings a warm, robust flavor to our dish
- Heavy cream. Cream is the key to our luscious, velvety sauce and pairs well with spicy recipes. If you're after a lighter version or need a dairy-free option, try almond or oat milk mixed with cornstarch. Coconut milk is another option; note that it will give a subtle tropical hint.
- Parmesan cheese. This jalapeno spaghetti has a salty, nutty, and umami kick. It enhances the overall flavor profile, taking it from delicious to genuinely delectable.
- Fresh parsley. It provides a beautiful color contrast and adds a hint of herbs, breaking through the rich and spicy flavors.

- Step 4. Add cooked spaghetti and cheddar cheese. Toss until evenly coated. And Enjoy

♨️How To Adjust The Heat?
This jalapeño spaghetti has a gentle warmth from fresh jalapeños, making it one of my favorite quick spicy dinner recipes. I like how easy it is to modify the spice, just adjust the number of peppers or how you handle the seeds.
- Mild: Use one jalapeño with seeds removed. You'll get light pepper flavor with a soft, comfortable warmth.
- Medium: Use two jalapeños and keep a few seeds. I find this level gives a pleasant kick without overpowering the creamy sauce.
- Extra Hot: Leave all seeds and membranes, and add another jalapeño or a serrano pepper for bold, lingering heat.
Variations
- Seafood. Try adding sautéed shrimp or calamari into the sauce.
- With veggies. Toss roasted vegetables like bell peppers, zucchini, or eggplant.
- For vegan. You can also sprinkle some nutritional yeast instead of Parmesan for a vegan alternative.
- Smoky Jalapeno Spaghetti. Give your dish a smoky spin by incorporating a touch of smoked paprika or chipotle(or with this jalapeno hot sauce). It adds a lovely depth of flavor and complements the heat of the jalapenos.
