Keto Broccoli Casserole Single Serve - A Cozy, Low-Carb Comfort Meal

Prep Time10 minutes mins

Cook Time25 minutes mins

Total Time35 minutes mins

Servings: 1 servings

Ingredients

• Broccoli florets (fresh or frozen, about 1 heaping cup)
• Heavy cream (2–3 tablespoons)
• Cream cheese (1 ounce, softened)
• Shredded cheddar (1/3 cup, divided)
• Grated Parmesan (1–2 tablespoons, optional for extra bite)
• Butter (1 teaspoon)
• Garlic powder (1/4 teaspoon)
• Onion powder (1/4 teaspoon)
• Ground mustard (a pinch, optional)
• Crushed red pepper flakes (a pinch, optional)
• Salt and black pepper (to taste)
• Cooked protein (optional): diced chicken, bacon bits, or sausage (2–3 tablespoons)
• Pork rinds or almond flour (optional) for a crunchy topping

Instructions

• Preheat and prep: Heat your oven to 375°F (190°C). Lightly grease a small oven-safe ramekin or mini baking dish (about 8–10 ounces) with butter or oil.
• Cook the broccoli: If using fresh, chop into small florets. Steam or microwave until just tender (bright green with a little bite), about 2–3 minutes. If using frozen, microwave until hot and drain very well. Pat dry with paper towels to prevent a watery casserole.
• Make the sauce: In a small bowl, combine heavy cream, softened cream cheese, half of the shredded cheddar, Parmesan (if using), garlic powder, onion powder, ground mustard, salt, and pepper. Microwave 20–30 seconds to loosen, then stir until smooth. Alternatively, warm gently in a small pan.
• Combine: Add the cooked broccoli to the ramekin. If using protein, fold it in now. Pour the cheese sauce over the top and toss gently to coat everything evenly.
• Top and finish: Sprinkle the remaining cheddar over the casserole. For crunch, mix 1 tablespoon crushed pork rinds or 1 teaspoon almond flour with a tiny bit of melted butter and sprinkle on top.
• Bake: Place the ramekin on a baking sheet and bake 12–15 minutes, until bubbly around the edges and the top is lightly browned. For extra color, broil for 1–2 minutes, watching closely.
• Rest and serve: Let it sit for 3–4 minutes to set and cool slightly. Finish with a crack of black pepper and a pinch of red pepper flakes if you like a little heat.

Storage Instructions

• Refrigerator: Store leftovers in an airtight container for up to 3 days. Reheat in the microwave in 30-second bursts or in the oven at 325°F (165°C) until warmed through.
• Freezer: You can freeze after baking and cooling.

  Wrap tightly and freeze up to 2 months. Thaw overnight in the fridge, then reheat in the oven for best texture.

• Make-ahead: Assemble the casserole (uncooked), cover, and refrigerate up to 24 hours. Bake straight from the fridge, adding 2–3 extra minutes.

Benefits of This Recipe

• Low-carb and keto-friendly: No flour thickeners or starchy add-ins.

  Each serving balances healthy fats, fiber, and protein.

• Single-serve convenience: Great for portion control and for anyone cooking for one.
• Customizable: Works with different cheeses, proteins, and spices without changing the core method.
• Fast and minimal cleanup: One bowl, one ramekin, and you’re done.
• Comfort-food vibes: Creamy, cheesy, and satisfying without the carb crash.

Common Mistakes to Avoid

• Skipping the drain: Wet broccoli waters down the sauce. Always drain and pat dry after cooking, especially with frozen broccoli.
• Using too large a dish: A bigger dish thins out the layer and dries the casserole. Use a small ramekin to keep it creamy and bubbly.
• Overcooking: Broccoli can go mushy fast.

  Aim for tender-crisp before baking, since it will cook more in the oven.

• Under-seasoning: Cheese and cream need a little salt, pepper, and aromatics to shine. Taste the sauce before baking and adjust.
• Cold cream cheese: It won’t blend smoothly. Soften it first or warm gently to avoid clumps.

Alternatives

• Cheese swaps: Try Monterey Jack for meltiness, gouda for smokiness, or pepper jack for heat.

  A little blue cheese crumbled in adds depth if that’s your style.

• Dairy-light version: Use half the heavy cream and add unsweetened almond milk or coconut cream. Note that coconut adds a mild sweetness, so bump up spices.
• Protein boost: Stir in rotisserie chicken, crumbled bacon, cooked ground turkey, or diced ham. Keep add-ins small so the casserole holds together.
• Veggie mix-ins: Add a few sautéed mushrooms, spinach, or riced cauliflower.

  Keep overall volume similar so the sauce-to-veg ratio stays creamy.

• Spice variations: Smoked paprika, Italian seasoning, or a dash of hot sauce can shift the flavor without changing the macros much.
• Air fryer method: Air fry at 350°F (175°C) for 8–10 minutes in an oven-safe dish that fits your basket. Check at 7 minutes.

FAQ

Can I use all frozen broccoli?

Yes. Microwave it until hot, then drain and press out excess moisture with paper towels.

The dryer the broccoli, the creamier the casserole.

What if I don’t have cream cheese?

You can use mascarpone, Boursin, or a little extra heavy cream with more cheddar. The sauce will be looser without cream cheese, so don’t overdo the cream.

How do I make it spicier?

Add red pepper flakes, a dash of cayenne, or use pepper jack cheese. A spoonful of green chiles also works well.

Can I double the recipe?

Absolutely.

Use a small baking dish, roughly 5×7 inches, and add a few minutes to the bake time. Keep an eye on the edges for bubbling.

Is this gluten-free?

Yes. There’s no flour or breadcrumbs in the base recipe.

If you use a crunchy topping, choose pork rinds or almond flour instead of regular crumbs.

What cheese melts best here?

Cheddar is classic, but gouda, fontina, or Monterey Jack melt beautifully. A blend of cheddar and mozzarella gives a stretchy, creamy finish.

How can I lower the calories a bit?

Use a little less cheese and swap part of the cream with unsweetened almond milk. You can also skip the crunchy topping and add more broccoli for volume.

Can I make it in the microwave?

Yes, but you’ll miss the browned top.

Cook the sauce and broccoli as directed, assemble in a microwave-safe dish, and heat in 30-second bursts until hot. Finish with a quick broil if you can.

What can I use instead of pork rinds for crunch?

Almond flour mixed with melted butter works well. You can also use crushed keto crackers or toasted chopped nuts for texture.

How do I keep the sauce from splitting?

Use gentle heat and stir well when making the sauce.

Avoid boiling the cream, and let the casserole rest a few minutes after baking to help it set.
