Keto Instant Pot Loaded Mac and Cheese

Rich and creamy mac and cheese made easy in the Instant Pot, loaded with crispy bacon, spicy jalapeños, and a trio of melted cheeses. The pressure cooking method creates perfectly tender pasta while the sautéed aromatics add depth of flavor. Topped with buttery panko breadcrumbs for textural contrast, this comfort food favorite is perfect for weeknight dinners or casual entertaining. The combination of cheddar, mozzarella, and Parmesan creates an irresistibly cheesy sauce, while fresh jalapeños provide just the right amount of heat to balance the richness.

FAQ
Can I use different pasta shapes?
Yes, but stick to similar-sized short pasta like penne or shells. Adjust cooking time by 1-2 minutes if needed.

Cook pasta separately, sauté aromatics in a large pot, then combine with cooked pasta, milk, and cheese over low heat.
How long will leftovers keep?
Refrigerate for up to 3 days. Reheat gently with a splash of milk to restore creaminess.
