What Ingredients You Will Need

This recipe uses straightforward, wholesome ingredients to bring out bold flavors and satisfying textures — all while keeping things paleo-friendly and nourishing. Most of these are kitchen staples, with a few fresh elements to keep it vibrant.

• Spaghetti Squash: One medium-sized (about 3-4 pounds), roasted and shredded into strands. This is the base of the casserole, offering a naturally sweet, low-carb alternative to pasta.
• Bacon: 6 strips, cooked crispy and chopped (adds smoky depth and a bit of crunch; go for nitrate-free if possible).
• Yellow Onion: 1 medium, finely chopped — caramelized for sweetness and body.
• Garlic: 3 cloves, minced — for that savory punch.
• Coconut Cream: 1 cup (full-fat, canned; I like Thai Kitchen brand for consistency) — creates the creamy paleo sauce.
• Nutritional Yeast: 1/3 cup — adds cheesy, nutty flavor without dairy.
• Almond Flour: 2 tablespoons — helps thicken the sauce and adds a subtle nuttiness.
• Chicken Broth: 1/2 cup (homemade or low-sodium store-bought) — for extra moisture and flavor.
• Spinach: 2 cups fresh, roughly chopped — adds color and nutrients.
• Green Onions: 2 stalks, sliced — for freshness and a mild oniony pop.
• Fresh Thyme: 1 teaspoon leaves, chopped (or 1/2 teaspoon dried) — for herbal brightness.
• Sea Salt & Black Pepper: To taste — essential seasoning for balance.
• Avocado Oil or Olive Oil: 2 tablespoons — for sautéing.

Optional: Feel free to swap in kale or Swiss chard if you don’t have spinach. For a dairy-free twist, coconut cream is your best bet for that luscious texture. And if you want a bit more heat, a pinch of red pepper flakes works wonders here.

Equipment Needed

• Baking Sheet: For roasting the spaghetti squash evenly.
• Large Skillet or Sauté Pan: For cooking bacon, onions, and spinach. A heavy-bottomed pan works best to avoid burning.
• Mixing Bowl: To combine the creamy sauce ingredients and mix everything together.
• Sharp Knife and Cutting Board: For chopping veggies and herbs.
• Fork or Spaghetti Squash Scraper: To shred the roasted squash strands easily.
• 9×13-inch Baking Dish: For assembling and baking the casserole.

If you don’t have a dedicated scraper for spaghetti squash, a fork works just fine — just be gentle to avoid mashing the strands. For roasting, I like using parchment paper on my baking sheet to prevent sticking and speed up cleanup. And if you’re on a budget, a simple cast-iron skillet doubles as a sauté pan and can last a lifetime — just season it well!

Preparation Method

1. Roast the Spaghetti Squash (40-50 minutes): Preheat your oven to 400°F (200°C). Cut the spaghetti squash in half lengthwise (careful, it can be tough!). Scoop out the seeds, then place the halves cut-side down on a parchment-lined baking sheet. Roast until tender — you’ll know it’s done when a fork easily pierces the skin and the strands separate easily (about 40-50 minutes).
2. Cook the Bacon (10 minutes): While the squash roasts, heat a large skillet over medium heat. Add bacon strips and cook until crisp. Remove bacon and place on paper towels to drain. Once cooled, chop into bite-sized pieces.
3. Sauté Onions, Garlic & Spinach (8-10 minutes): In the same skillet, discard excess bacon fat, leaving about 1 tablespoon for flavor. Add avocado oil if needed. Toss in chopped onions and cook over medium heat until caramelized and golden, about 5-7 minutes. Add minced garlic and cook for 1 more minute, then stir in fresh spinach until wilted.
4. Prepare the Creamy Sauce (3-5 minutes): In a mixing bowl, whisk together coconut cream, nutritional yeast, almond flour, chicken broth, thyme, salt, and pepper until smooth. This sauce should be thick but pourable — if too thick, add a splash more broth.
5. Combine Casserole Ingredients (5 minutes): Once the squash is cool enough to handle, scrape the strands into a large bowl. Add the sautéed veggies, chopped bacon, green onions, and creamy sauce. Mix gently until everything is evenly coated.
6. Assemble and Bake (25-30 minutes): Transfer the mixture into a greased 9×13-inch baking dish. Smooth the top and bake at 375°F (190°C) for 25-30 minutes until bubbly and golden on top. You’re looking for a lightly browned crust and a warm, creamy center.
7. Rest and Serve (5 minutes): Let the casserole sit for a few minutes before serving — this helps it set and makes serving easier.

Pro tip: If your sauce seems too watery before baking, a quick simmer in the skillet for a few minutes can thicken it up nicely. Also, be patient with the squash — overcooking can make it mushy, undercooking means tough strands, so test early and often!

Cooking Tips & Techniques

Making a creamy paleo casserole doesn’t have to be intimidating, but I’ve learned some tricks that really make a difference. First, roasting the spaghetti squash cut-side down traps steam and cooks it evenly — trust me, it’s the best way to get those perfect strands every time. Also, caramelizing the onions slowly brings out their natural sweetness, which balances the smoky bacon and tangy nutritional yeast sauce.

One mistake I made early on was adding too much liquid to the sauce. Remember, coconut cream is rich and thick, so a little goes a long way. If it’s too runny, the casserole won’t set properly. You can always thin it with broth, but never the other way around!

When baking, keep an eye on the top — if it’s browning too fast, loosely cover with foil to avoid burning. And if you want a crispier top, a quick broil for 2-3 minutes at the end works wonders (don’t walk away!).

Lastly, multitasking helps speed things up — start the squash in the oven, then cook bacon, and prep the sauce while waiting. It’s surprisingly satisfying to see it all come together without a mad rush.

Variations & Adaptations

• Vegetarian Version: Skip the bacon and add roasted mushrooms or walnuts for a hearty texture and umami flavor.
• Seasonal Veggie Swap: In fall, toss in roasted butternut squash cubes or Brussels sprouts. In spring, fresh asparagus tips work beautifully.
• Spice it Up: Add a pinch of smoked paprika or cayenne pepper to the sauce for a subtle kick that complements the creamy base.

For different cooking methods, you can microwave the spaghetti squash to save time (pierce the skin and cook on high for 10-12 minutes), but roasting gives the best flavor. If you’re avoiding nuts, substitute almond flour with cassava or arrowroot flour to keep it paleo-friendly.

Personally, I once made this casserole with turkey bacon and swapped spinach for kale — it was just as tasty but with a bit more bite. Feel free to play around with ingredients to suit your pantry and taste buds.

Serving & Storage Suggestions

This casserole is best served warm, straight from the oven, but it also holds up well the next day. I like sprinkling fresh herbs like parsley or chives on top for a pop of color and freshness before serving. Pair it with a crisp green salad or steamed vegetables for a balanced meal.

Store leftovers in an airtight container in the fridge for up to 4 days. Reheat gently in the oven at 350°F (175°C) or in a skillet over low heat to keep the creamy texture intact. Avoid microwaving for long stretches or the sauce might separate.

Freezing is possible too — portion into freezer-safe containers and thaw overnight in the fridge before reheating. The flavors actually meld beautifully over time, making leftovers even better the next day.

Nutritional Information & Benefits

This Creamy Paleo Loaded Spaghetti Squash Casserole is a nutrient-packed option, rich in fiber and vitamins from the squash and spinach. The dish is naturally gluten-free, grain-free, and dairy-free, making it suitable for many dietary needs.

Thanks to the use of nutritional yeast, you get a boost of B vitamins and a cheesy flavor without dairy, which helps those with lactose intolerance. The combination of veggies and protein supports balanced energy levels, and the almond flour adds a touch of nuttiness plus texture without gluten.

Nutritional yeast offers a unique cheesy flavor, but if you can’t find it, a pinch of smoked paprika or turmeric can add depth, though the cheesy note will be missing.

Can I use frozen spinach instead of fresh?

Yes, just thaw and squeeze out excess moisture before adding to prevent a watery casserole.

What if I don’t like bacon? What can I use instead?

Try sautéed mushrooms, diced roasted sweet potatoes, or toasted nuts for a smoky or crunchy element without the meat.
