What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and you can swap a few depending on what you have on hand.

• Spaghetti: 12 ounces (340 grams), cooked al dente (I prefer Barilla for consistent texture)
• Bacon: 8 slices, cooked crispy and chopped (thick-cut works best for that smoky crunch)
• Cream Cheese: 8 ounces (225 grams), softened (adds richness and creaminess)
• Sour Cream: 1 cup (240 ml) (use full-fat for best flavor; dairy-free options work too)
• Sharp Cheddar Cheese: 2 cups (200 grams), shredded (for that punch of flavor)
• Mozzarella Cheese: 1 cup (100 grams), shredded (melts beautifully for gooey texture)
• Eggs: 2 large, beaten (room temperature, helps hold everything together)
• Garlic Powder: 1 teaspoon (adds subtle depth)
• Onion Powder: 1 teaspoon (for savory notes)
• Salt & Pepper: to taste
• Milk or Heavy Cream: 1/2 cup (120 ml) (makes the sauce silky; use cream for extra richness)
• Chopped Fresh Parsley: Optional, for garnish and a pop of color

Substitution tips: Use gluten-free pasta for dietary needs or swap sour cream with Greek yogurt if you want a tangier twist. I’ve also tried adding a pinch of smoked paprika for a smoky undertone that works wonders.

Equipment Needed

• Large Pot: For boiling the spaghetti (a sturdy one with plenty of water helps prevent sticking)
• Skillet or Frying Pan: To cook the bacon crisp (cast iron is my go-to for even heat)
• Mixing Bowls: At least two—one for the sauce mixture and one for the pasta
• 9×13-inch Baking Dish: Perfect size for layering and baking the casserole
• Wooden Spoon or Silicone Spatula: For mixing ingredients gently without breaking the pasta
• Measuring Cups and Spoons: For accuracy (especially with seasoning and liquids)

If you’re on a budget, you can use a non-stick baking dish and a regular frying pan instead of cast iron. Just make sure your bacon gets nice and crispy because that texture is a game-changer. Also, keep your mixing bowls handy—trust me, it saves time and mess!

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease your 9×13-inch baking dish lightly with butter or non-stick spray.
2. Cook the spaghetti: Bring a large pot of salted water to a boil. Add 12 ounces (340 g) spaghetti and cook until al dente—about 8 to 9 minutes. Drain well and set aside. (Tip: Toss pasta with a little olive oil after draining to keep strands from sticking.)
3. Prepare the bacon: In a skillet over medium heat, cook 8 slices of thick-cut bacon until crisp, about 6-8 minutes. Transfer to paper towels to drain, then chop into bite-sized pieces. Save a teaspoon of bacon fat for extra flavor if you like.
4. Mix the creamy sauce: In a large mixing bowl, combine 8 ounces (225 g) softened cream cheese, 1 cup (240 ml) sour cream, 1/2 cup (120 ml) milk or heavy cream, and 2 beaten large eggs. Whisk together until smooth and creamy.
5. Add seasoning and cheese: Stir in 1 teaspoon garlic powder, 1 teaspoon onion powder, salt and pepper to taste, 2 cups (200 g) shredded sharp cheddar, and 1 cup (100 g) shredded mozzarella. Mix until cheese is evenly distributed.
6. Combine pasta and bacon: Fold the cooked spaghetti and chopped bacon into the creamy mixture. If you saved bacon fat, drizzle it in here for a flavor boost. Mix gently but thoroughly.
7. Transfer to baking dish: Pour the mixture into your prepared baking dish, spreading it out evenly. Sprinkle a little extra shredded cheddar or mozzarella on top for a golden crust.
8. Bake uncovered in the preheated oven for 25-30 minutes, until bubbly and the top is lightly browned. (If you like it crispier, broil for the last 2 minutes—just watch it closely!)
9. Rest and garnish: Remove from oven and let it rest for 5 minutes. This helps the casserole set up nicely. Sprinkle chopped fresh parsley on top before serving for a fresh touch.

Pro tip: If your sauce looks too thick before baking, add a splash more milk to loosen it up. Also, avoid overmixing the pasta to keep it from getting mushy. The texture is key here!

Cooking Tips & Techniques

Honestly, making this casserole is pretty straightforward, but a few tricks make all the difference. First, don’t skimp on cooking the bacon crispy. The contrast between creamy and crunchy is what makes this dish sing. I’ve learned the hard way that undercooked bacon just turns soggy in the sauce, and that’s a bummer.

Another tip: soften your cream cheese before mixing. Cold cream cheese can cause lumps and uneven texture. I usually leave it out on the counter for 20-30 minutes or zap it in the microwave for 10 seconds (don’t overdo it!).

Timing is everything. Cook your spaghetti just shy of al dente since it’ll finish cooking in the oven. Overcooked pasta turns mushy, and frankly, no one wants that. Also, mixing the sauce and pasta gently helps keep the noodles intact—let’s face it, nobody wants a pasta mush fest.

When it comes to seasoning, don’t be shy. The cheese adds saltiness, but a pinch of black pepper and garlic powder really lift the flavors. I once made this without onion powder, and it was a little flat—lesson learned!

Lastly, give the casserole a little rest after baking. Cutting into it too soon leads to a soupy mess. Waiting helps it set up, making serving cleaner and more enjoyable.

Variations & Adaptations

This Creamy Million Dollar Spaghetti Casserole with Crispy Bacon is a flexible recipe that you can tweak to fit your tastes or dietary needs.

• Vegetarian Version: Skip the bacon and add sautéed mushrooms or caramelized onions for a smoky, meaty flavor without the pork.
• Low-Carb Option: Swap spaghetti for spiralized zucchini noodles or shirataki noodles. Be sure to reduce baking time as these cook faster.
• Spicy Kick: Add a teaspoon of red pepper flakes or diced jalapeños to the sauce for a subtle heat that pairs well with the bacon.
• Dairy-Free Adaptation: Use dairy-free cream cheese and sour cream alternatives, plus a vegan cheese blend. I tried this once with cashew cream, and it was surprisingly creamy!
• Different Cheese Blends: Try mixing in smoked gouda or parmesan for a deeper, nuttier flavor.

One of my favorite tweaks is adding chopped fresh spinach into the mix before baking. It sneaks in some greens without overpowering the dish, and the cream sauce keeps it from drying out.

Serving & Storage Suggestions

This casserole shines best served hot and bubbly, right out of the oven. I like to pair it with a crisp green salad or steamed veggies to balance all that creamy goodness. A simple side of garlic bread or a glass of chilled white wine also pairs beautifully, making it a cozy dinner that feels a bit fancy.

Leftovers? No problem. Store them in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of milk to keep the sauce creamy, and warm it gently in the oven or microwave. Avoid overheating, or the cheese can get rubbery.

If you want to freeze this casserole, bake it first, then cool completely. Wrap tightly with foil and freeze for up to 2 months. Reheat covered at 350°F (175°C) until warmed through, about 25-30 minutes.

Fun fact: the flavors actually deepen after resting overnight, so sometimes I make it a day ahead for an even tastier meal the next day.
