3. While potatoes roast, heat a skillet over medium heat and add a touch of oil. Sauté onion until translucent, 4–5 minutes.
4. Add garlic, minced chipotle peppers and adobo sauce, cumin, and smoked paprika. Cook 1 minute until fragrant.
5. Stir in black beans and corn, warm through, and season with salt and pepper. Remove from heat.
6. Reduce oven to 375°F (190°C). Pour about 1/2 cup enchilada sauce into the bottom of the prepared baking dish.
7. Layer tortillas to cover the bottom (tear to fit), spoon on one-third of the sweet potatoes, half the bean–corn mixture, a sprinkle of cheese, and 1/3 cup enchilada sauce.
8. Repeat: another tortilla layer, remaining sweet potatoes, remaining bean mixture, more cheese, and another 1/3 cup sauce.
9. Top with a final layer of tortillas, the remaining enchilada sauce spread over, and the remaining cheese.
10. Cover with foil and bake 20 minutes. Remove foil and bake an additional 10 minutes until cheese is bubbly and casserole is heated through.
11. Let rest 5 minutes, then sprinkle with chopped cilantro if using.
12. Serve slices topped with sour cream, avocado, and lime wedges for brightness.

Ham and Asparagus Tetrazzini

Creamy, cheesy comfort with tender ham and bright asparagus—perfect for a festive weeknight or holiday side.

Ingredients:

• 12 oz spaghetti or linguine
• 2 cups cooked ham, diced
• 1 lb asparagus, trimmed and cut into 1–2 inch pieces
• 2 tbsp butter
• 2 tbsp all-purpose flour
• 2 cups milk (whole or 2%)
• 1 cup heavy cream or half-and-half
• 1 cup grated Parmesan cheese
• 1 cup shredded mozzarella (plus extra for topping, optional)
• 1/2 tsp Dijon mustard (optional)
• 1/4 tsp nutmeg (optional)
• Salt and black pepper, to taste
• 1/2 cup breadcrumbs (panko or regular) for topping
• 2 tbsp chopped fresh parsley (optional, for garnish)
• Olive oil or cooking spray for dish

How to Make:

1. Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Cook pasta in salted boiling water until just shy of al dente (about 1–2 minutes less than package directions). Drain and set aside.
3. Meanwhile, blanch asparagus in boiling water for 2–3 minutes until bright green and slightly tender. Drain and plunge into cold water to stop cooking; drain again.
4. In a medium saucepan, melt butter over medium heat. Stir in flour and cook 1 minute until bubbly.
5. Gradually whisk in milk and cream, smoothing out lumps. Cook, stirring, until the sauce thickens and coats the back of a spoon (3–5 minutes).
6. Remove sauce from heat and stir in Parmesan, mozzarella, Dijon, nutmeg, salt, and pepper. Taste and adjust seasoning.
7. In a large bowl, combine cooked pasta, diced ham, and asparagus. Pour the cheese sauce over and toss gently to coat everything evenly.
8. Transfer the mixture to the prepared baking dish and spread level. Sprinkle breadcrumbs and extra mozzarella over the top if using.
9. Bake uncovered for 20–25 minutes, until bubbly and golden on top. If you like extra browning, broil 1–2 minutes—watch closely.
10. Let rest 5 minutes, sprinkle with chopped parsley, slice, and serve.

Enjoy a slice of cozy, cheesy goodness that’s sure to disappear fast!
