This low carb yellow squash casserole with taco flavor is my go to summer recipe when I have more squash than I know what to do with. It turns simple ingredients into a cheesy savory bake that always disappears fast at potlucks and family dinners. No special skills or complicated prep just fresh flavors and lots of melty cheese.

The first time I tried this casserole was after harvesting squash from my garden it instantly became a family favorite even with my kids who usually do not like squash dishes

Ingredients

  • Summer squash thinly sliced: Choose firm squash with shiny skin and no soft spots for the best texture
  • Canned diced tomato: Adds moisture and an acid kick Go for no salt added if you want to control the seasoning
  • Ground beef cooked and drained: Lean beef keeps things lighter Look for meat with bright red color and minimal liquid in the package
  • Chili powder: Gives that essential taco backbone Use a blend without fillers for the best punch
  • Paprika: Adds smokiness Opt for a deep red Spanish paprika if available
  • Cumin: Brings earthiness and classic taco flavor Freshly ground cumin is more aromatic
  • Onion powder: Adds sweetness and depth without the fuss of chopping and sautéing fresh onions
  • Garlic salt: Seasons and builds complexity Use a garlic salt with real garlic for stronger flavor
  • Salt: Brings out all other flavors A fine grain sea salt blends easily
  • Cayenne: Adds heat and complexity Add a touch more if you want extra spice
  • Cheddar cheese grated: The gooey finish Pick a good sharp cheddar and grate it yourself for melty results

Step-by-Step Instructions

Prepare the Oven and Pan:
Preheat your oven to 350 degrees Arrange your oven rack to the middle for even baking Lightly grease a nine by thirteen inch baking pan so nothing sticks
Simmer the Taco Meat Mixture:
Combine the cooked and drained ground beef with canned diced tomatoes chili powder paprika cumin onion powder garlic salt salt and cayenne in a large skillet Bring it to a gentle simmer over medium heat for about five minutes This step allows all the taco spices to bloom and mingle with the tomatoes resulting in a super flavorful meat mixture
Layer the Squash:
Lay the thinly sliced squash in a single even layer across the bottom of your prepared baking pan Do not overlap too much This helps the squash cook evenly and prevents sogginess
Add the Meat Mixture:
Pour the meat mixture directly on top of the squash layer Spreading it gently with a spatula ensures all the squash has a bit of meat on top which makes every bite flavorful
Top with Cheese:
Evenly sprinkle the grated cheddar cheese over the meat and squash layers Try to cover the full surface for the best cheese pull later
Bake Until Golden:
Slide the pan into the preheated oven Bake for around twenty five minutes or until the cheese is totally melted and bubbling and the edges start to look golden brown Let it rest five minutes before cutting This helps it firm up for neater slices

Storage Tips

This casserole keeps well covered in the refrigerator for up to four days For longer storage freeze individual slices wrapped tightly in foil or in airtight containers To reheat just microwave or pop into a warm oven until heated through Cheese might crisp up more on the second round which can be really tasty

Ingredient Substitutions

If you run out of summer squash zucchini works just as well For a vegetarian twist swap the ground beef for a hearty plant based crumble or cooked lentils You can also use Monterey Jack or a Mexican blend in place of the cheddar cheese if that is what you have

Serving Suggestions

Serve it with a simple green salad and maybe a scoop of guacamole on the side It also pairs well with cauliflower rice or crisp tortilla chips for the carb eaters at your table For an extra kick drizzle with hot sauce or sprinkle sliced green onions on top right before serving

Recipe FAQs

→ How do I prevent watery casserole?

After slicing squash, sprinkle it lightly with salt and let it rest for 10-15 minutes. Pat dry before using, or grill the slices first to remove excess water.

→ Can I substitute the ground beef?

Yes. Ground turkey or chicken makes a lighter alternative, or use ground pork for a different flavor twist.

→ What cheese works best?

Sharp cheddar provides excellent melting and robust taste. Monterey Jack or a Mexican blend also complements the taco spices well.

→ How spicy is the finished dish?

The level of heat is mild, but you can increase it by adding extra cayenne or chopped green chilis to suit your preference.

→ Can leftovers be stored and reheated?

Absolutely. Store in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through.
